    Several vulnerabilities have been discovered in the Linux kernel that     may lead to privilege escalation, denial of service or information     leaks.

    CVE-2021-4159

        A flaw was found in the eBPF verifier which could lead to an         out-of-bounds read.  If unprivileged use of eBPF is enabled, this         could leak sensitive information.  This was already disabled by         default, which would fully mitigate the vulnerability.

    CVE-2021-33655

        A user with access to a framebuffer console device could cause a         memory out-of-bounds write via the FBIOPUT_VSCREENINFO ioctl.

    CVE-2021-33656

        A user with access to a framebuffer console device could cause a         memory out-of-bounds write via some font setting ioctls.  These         obsolete ioctls have been removed.

    CVE-2022-1462

         reported a race condition in the pty (pseudo-terminal)         subsystem that can lead to a slab out-of-bounds write.  A local         user could exploit this to cause a denial of service (crash or         memory corruption) or possibly for privilege escalation.

    CVE-2022-1679

        The syzbot tool found a race condition in the ath9k_htc driver         which can lead to a use-after-free.  This might be exploitable to         cause a denial service (crash or memory corruption) or possibly         for privilege escalation.

    CVE-2022-2153

        kangel reported a flaw in the KVM implementation for x86         processors which could lead to a null pointer dereference. A local         user permitted to access /dev/kvm could exploit this to cause a         denial of service (crash).

    CVE-2022-2318

        A use-after-free in the Amateur Radio X.25 PLP (Rose) support may         result in denial of service.

    CVE-2022-2586

        A use-after-free in the Netfilter subsystem may result in local         privilege escalation for a user with the CAP_NET_ADMIN capability         in any user or network namespace.

    CVE-2022-2588

        Zhenpeng Lin discovered a use-after-free flaw in the cls_route         filter implementation which may result in local privilege         escalation for a user with the CAP_NET_ADMIN capability in any         user or network namespace.

    CVE-2022-2663

        David Leadbeater reported flaws in the nf_conntrack_irc         connection-tracking protocol module.  When this module is enabled         on a firewall, an external user on the same IRC network as an         internal user could exploit its lax parsing to open arbitrary TCP         ports in the firewall, to reveal their public IP address, or to         block their IRC connection at the firewall.

    CVE-2022-3028

        Abhishek Shah reported a race condition in the AF_KEY subsystem,         which could lead to an out-of-bounds write or read.  A local user         could exploit this to cause a denial of service (crash or memory         corruption), to obtain sensitive information, or possibly for         privilege escalation.

    CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742

        Roger Pau Monne discovered that Xen block and network PV device         frontends don't zero out memory regions before sharing them with         the backend, which may result in information disclosure.
        Additionally it was discovered that the granularity of the grant         table doesn't permit sharing less than a 4k page, which may also         result in information disclosure.

    CVE-2022-26373

        It was discovered that on certain processors with Intel's Enhanced         Indirect Branch Restricted Speculation (eIBRS) capabilities there         are exceptions to the documented properties in some situations,         which may result in information disclosure.

        Intel's explanation of the issue can be found at         https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-     guidance/advisory-guidance/post-barrier-return-stack-buffer-predictions.html

    CVE-2022-33744

        Oleksandr Tyshchenko discovered that ARM Xen guests can cause a         denial of service to the Dom0 via paravirtual devices.

    CVE-2022-36879

        A flaw was discovered in xfrm_expand_policies in the xfrm         subsystem which can cause a reference count to be dropped twice.

    CVE-2022-36946

        Domingo Dirutigliano and Nicola Guerrera reported a memory         corruption flaw in the Netfilter subsystem which may result in         denial of service.

    CVE-2022-39188

        Jann Horn reported a race condition in the kernel's handling of         unmapping of certain memory ranges.  When a driver created a         memory mapping with the VM_PFNMAP flag, which many GPU drivers do,         the memory mapping could be removed and freed before it was         flushed from the CPU TLBs.  This could result in a page use-after-         free.  A local user with access to such a device could exploit         this to cause a denial of service (crash or memory corruption) or         possibly for privilege escalation.

    CVE-2022-39842

        An integer overflow was discovered in the pxa3xx-gcu video driver         which could lead to a heap out-of-bounds write.

        This driver is not enabled in Debian's official kernel         configurations.

    CVE-2022-40307

        A race condition was discovered in the EFI capsule-loader driver,         which could lead to use-after-free.  A local user permitted to         access this device (/dev/efi_capsule_loader) could exploit this to         cause a denial of service (crash or memory corruption) or possibly         for privilege escalation.  However, this device is normally only         accessible by the root user.

    For Debian 10 buster, these problems have been fixed in version     4.19.260-1.

    We recommend that you upgrade your linux packages.

    Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to     unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend     (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)

  - Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution     under certain microarchitecture-dependent conditions. (CVE-2022-29900)

  - Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their     retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can     hijack return instructions to achieve arbitrary speculative code execution under certain     microarchitecture-dependent conditions. (CVE-2022-29901)

  - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of     a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:2736 advisory.

  - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result     in data leakage. (CVE-2021-26341)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were     built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of     bytes located in supposedly non-executable regions of a file. (CVE-2022-25265)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers     em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system     or potentially escalate their privileges on the system. (CVE-2022-3239)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations. (CVE-2022-39189)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused     by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

  - An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could     cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. (CVE-2022-41674)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

  - Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through     5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-     free conditions to potentially execute code. (CVE-2022-42720)

  - A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before     5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in     turn, potentially execute code. (CVE-2022-42721)

  - In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the     mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon     protection of P2P devices. (CVE-2022-42722)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:2951 advisory.

  - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result     in data leakage. (CVE-2021-26341)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were     built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of     bytes located in supposedly non-executable regions of a file. (CVE-2022-25265)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers     em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system     or potentially escalate their privileges on the system. (CVE-2022-3239)

  - A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs     when a user connects to a malicious USB device. This can allow a local user to crash the system or     escalate their privileges. (CVE-2022-3628)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations. (CVE-2022-39189)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused     by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

  - An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could     cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. (CVE-2022-41674)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

  - Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through     5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-     free conditions to potentially execute code. (CVE-2022-42720)

  - A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before     5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in     turn, potentially execute code. (CVE-2022-42721)

  - In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the     mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon     protection of P2P devices. (CVE-2022-42722)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux     kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an     invalid pointer request. (CVE-2023-1195)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)
