The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/radeon: Add the missed acpi_put_table() to fix memory leak When the radeon driver reads the bios     information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the     ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak. v2: fix text     formatting (Alex) (CVE-2022-50275)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.4.231-137.341. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-042 advisory.

    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)

    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)

    In the Linux kernel, the following vulnerability has been resolved:

    hfs: fix OOB Read in __hfs_brec_find (CVE-2022-50581)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    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)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    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 memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

    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)

    atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

The version of kernel installed on the remote host is prior to 4.14.304-226.531. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1932 advisory.

    Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior. (CVE-2022-3643)

    Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
    the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced     another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the     XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock     could occur in case of netpoll being active for the interface the xen-netback driver is connected to     (CVE-2022-42329). (CVE-2022-42328)

    In the Linux kernel, the following vulnerability has been resolved:

    hfs: fix OOB Read in __hfs_brec_find (CVE-2022-50581)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    There is a logic error in io_uring's implementation which can be used to trigger a use-after-free     vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the     last io_grab_identity call cannot return false is not true, and in this case the function will use the     init_cred or the previous linked requests identity to do operations instead of using the current identity.
    This can lead to reference counting issues causing use-after-free. We recommend upgrading past version     5.10.161. (CVE-2023-0240)

    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)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    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)

    efi: rt-wrapper: Add missing include (CVE-2023-21102)

    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)

    atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)
