Publication date: 25 Aug 2022

Type: security
Affected Mageia releases: 8
CVE: CVE-2022-1679,
     CVE-2022-2585,

     CVE-2022-2588,
     CVE-2022-26373

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 timersfunctionality 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).

x86/bugs: Enable STIBP for IBPB mitigated RETBleed.
