Description

**Issue Overview:** 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 flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. (CVE-2022-2153) 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 flaw was found in hw. Non-transparent sharing of branch predictor targets between contexts in some Intel(R) processors may potentially allow an authorized user to enable information disclosure via local access. (CVE-2022-29901) A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
