CVE-2022-1199, CVE-2022-1204, CVE-2022-1205 Duoming Zhou discovered race conditions     in the AX.25 hamradio protocol, which could lead to a use-after-free or null pointer dereference. A local     user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2022-1353 The TCS Robot tool found an information leak in the PF_KEY subsystem.
    A local user can receive a netlink message when an IPsec daemon registers with the kernel, and this could     include sensitive information. CVE-2022-1419 Minh Yuan discovered a race condition in the vgem virtual GPU     driver that can lead to a use-after-free. A local user permitted to access the GPU device can exploit this     to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.
    CVE-2022-1516 A NULL pointer dereference flaw in the implementation of the X.25 set of standardized     network protocols, which can result in denial of service. This driver is not enabled in Debian's official     kernel configurations. CVE-2022-1652 Minh Yuan discovered a race condition in the floppy driver that can     lead to a use-after-free. A local user permitted to access a floppy drive device can exploit this to cause     a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-1729     Norbert Slusarek discovered a race condition in the perf subsystem which could result in local privilege     escalation to root. The default settings in Debian prevent exploitation unless more permissive settings     have been applied in the kernel.perf_event_paranoid sysctl. CVE-2022-1734 Duoming Zhou discovered race     conditions in the nfcmrvl NFC driver that could lead to a use-after-free, double-free or null pointer     dereference. A local user might be able to exploit these for denial of service (crash or memory     corruption) or possibly for privilege escalation. This driver is not enabled in Debian's official kernel     configurations. CVE-2022-1974, CVE-2022-1975 Duoming Zhou discovered that the NFC netlink interface was     suspectible to denial of service. 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-2022-21123, CVE-2022-21125, CVE-2022-21166 Various     researchers discovered flaws in Intel x86 processors, collectively referred to as MMIO Stale Data     vulnerabilities. These are similar to the previously published Microarchitectural Data Sampling (MDS)     issues and could be exploited by local users to leak sensitive information. For some CPUs, the mitigations     for these issues require updated microcode. An updated intel-microcode package may be provided at a later     date. The updated CPU microcode may also be available as part of a system firmware (BIOS) update.
    Further information on the mitigation can be found at https://www.kernel.org/doc/html/latest/admin-     guide/hw-vuln/processor_mmio_stale_data.html or in the linux-doc-4.19 package. CVE-2022-23960 Researchers     at VUSec discovered that the Branch History Buffer in Arm processors can be exploited to create     information side channels with speculative execution. This issue is similar to Spectre variant 2, but     requires additional mitigations on some processors. This was previously mitigated for 32-bit Arm (armel     and armhf) architectures and is now also mitigated for 64-bit Arm (arm64). This can be exploited to obtain     sensitive information from a different security context, such as from user-space to the kernel, or from a     KVM guest to the kernel. CVE-2022-26490 Buffer overflows in the STMicroelectronics ST21NFCA core driver     can result in denial of service or privilege escalation. This driver is not enabled in Debian's official     kernel configurations. CVE-2022-27666 valis reported a possible buffer overflow in the IPsec ESP     transformation code.

    CVE-2022-30594 Jann Horn discovered a flaw in the interaction between ptrace and seccomp subsystems. A     process sandboxed using seccomp() but still permitted to use ptrace() could exploit this to remove the     seccomp restrictions. CVE-2022-32250 Aaron Adams discovered a use-after-free in Netfilter which may result     in local privilege escalation to root. CVE-2022-33981 Yuan Ming from Tsinghua University reported a race     condition in the floppy driver involving use of the FDRAWCMD ioctl, which could lead to a use-after-free.
    A local user with access to a floppy drive device could exploit this to cause a denial of service (crash     or memory corruption) or possibly for privilege escalation. This ioctl is now disabled by default. For the     oldstable distribution (buster), these problems have been fixed in version 4.19.249-2. Due to an issue in     the signing service (Cf. Debian bug #1012741), the vport-vxlan module cannot be loaded for the signed     kernel for amd64 in this update. This update also corrects a regression in the network scheduler subsystem     (bug #1013299). For the 32-bit Arm (armel and armhf) architectures, this update enables optimised     implementations of several cryptographic and CRC algorithms. For at least AES, this should remove a timing     sidechannel that could lead to a leak of sensitive information. This update includes many more bug fixes     from stable updates 4.19.236-4.19.249 inclusive, including for bug #1006346. The random driver has been     backported from Linux 5.19, fixing numerous performance and correctness issues. Some changes will be     visible: The entropy pool size is now 256 bits instead of 4096. You may need to adjust the configuration     of system monitoring or user-space entropy gathering services to allow for this. On systems without a     hardware RNG, the kernel may log more uses of /dev/urandom before it is fully initialised. These uses were     previously under-counted and this is not a regression. We recommend that you upgrade your linux packages.

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)

  - An out-of-bounds read flaw was found in the Linux kernel's io_uring module in the way a user triggers the     io_read() function with some special parameters. This flaw allows a local user to read some memory out of     bounds. (CVE-2022-1508)

  - A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function     in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to     leak unauthorized kernel information, causing a denial of service. (CVE-2022-1651)

  - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency     use-after-free flaw in the bad_flp_intr function.

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use     after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - 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)

  - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of     service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal     instruction in guest in the Intel CPU. (CVE-2022-1852)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that     allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)

  - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of     the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)

  - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text     explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device     frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).
    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)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has     EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring     timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race     condition perhaps can only be exploited infrequently. (CVE-2022-29582)

  - 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)

  - 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)

  - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data     Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further     processing to nevertheless be freed. (CVE-2022-33743)

  - 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.
    (CVE-2022-33981)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)

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

Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
