CVE-2022-3176

Vulnerability Summary

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) 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 malicious user 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 user to crash the system and possibly lead to a local privilege escalation problem. (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) A firewall flaw that can bypass the Linux kernel's Netfilter functionality was found in how a user handles unencrypted IRC with nf_conntrack_irc configured. This flaw allows a remote user to gain unauthorized access to the system. (CVE-2022-2663) An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905) 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 malicious user 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) A use-after-free flaw was found in io_uring in the Linux kernel. This flaw allows a local user to trigger the issue if a signalfd or binder fd is polled with the io_uring poll due to a lack of io_uring POLLFREE handling. (CVE-2022-3176) A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member of the audio group) could use this flaw to crash the system, resulting in a denial of service condition. (CVE-2022-3303) A flaw was found in the x86 KVM subsystem in kvm_steal_time_set_preempted in arch/x86/kvm/x86.c in the Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189) An issue exists in net/netfilter/nf_tables_api.c in the Linux kernel prior to 5.19.6. A denial of service can occur upon binding to an already bound chain. (CVE-2022-39190) A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to crash the system. (CVE-2022-40307)
