CVE-2022-36946

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.

The Linux Kernel, the operating system core itself.

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)

io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859(CVE-2022-2327)

An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-2639)

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

This kernel update is based on upstream 5.15.58 and fixes at least the following security issues:

Kernel lockdown bypass when UEFI secure boot is disabled / unavailable and IMA appraisal is enabled (CVE-2022-21505).

Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure (CVE-2022-23825).

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

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 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges (CVE-2022-36123).

An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice (CVE-2022-36879).

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).

Other fixes in this update:

• fs: sendfile handles O_NONBLOCK of out_fd
• hugetlb: fix memoryleak in hugetlb_mcopy_atomic_pte
• mm: fix page leak with multiple threads mapping the same page
• x86/bugs: Do not enable IBPB at firmware entry when IBPB is not available
• x86/speculation: Make all RETbleed mitigations 64-bit only

For other upstream fixes, see the referenced changelogs.

This kernel update is based on upstream 5.15.62 and fixes at least the following security issues:

A use-after-free flaw was found in the Linux kernel 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).

A use-after-free flaw was found in the Linux kernel’s POSIX CPU timers functionality in the way a user creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2022-2585).

A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation (CVE-2022-2586).

A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local, privileged attacker to crash the system, possibly leading to a local privilege escalation issue (CVE-2022-2588).

A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation (eIBRS) capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer (RSB) prediction (CVE-2022-26373).

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).

x86/bugs: Enable STIBP for IBPB mitigated RETBleed.

Other fixes in this update:

• add support for more tcp congestion control algos (mga #30725)

For other upstream fixes in this update, see the referenced changelogs.
