Security update for the Linux Kernel
The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre like Branch Target Buffer attack, that can leak arbitrary kernel information (bsc#1199657).
- CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages (bsc#1199487).
- CVE-2022-20132: Fixed out of bounds read due to improper input validation in lg_probe and related functions of hid-lg.c (bsc#1200619).
- CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)
- CVE-2022-20141: Fixed a possible use after free due to improper locking in ip_check_mc_rcu() (bsc#1200604).
- CVE-2021-4157: Fixed an out of memory bounds write flaw in the NFS subsystem, related to the replication of files with NFS. A user could potentially crash the system or escalate privileges on the system (bsc#1194013).
- CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050).
- CVE-2017-16525: Fixed a use-after-free after failed setup in usb/serial/console (bsc#1066618).
The following non-security bugs were fixed:
- exec: Force single empty string when argv is empty (bsc#1200571).

Описание
The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel before 4.13.8 allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup.

Описание
An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system.

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.

Описание
In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel

Описание
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.
