Security update for the Linux Kernel (Live Patch 7 for SLE 15 SP4)

This update for the Linux Kernel 5.14.21-150400_24_41 fixes several issues.

The following security issues were fixed:

  • CVE-2023-26545: Fixed double free in net/mpls/af_mpls.c upon an allocation failure (bsc#1208700).
  • CVE-2023-1078: Fixed a heap out-of-bounds write in rds_rm_zerocopy_callback (bsc#1208838).
  • CVE-2023-0266: Fixed a use-after-free vulnerability inside the ALSA PCM package. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 was missing locks that could have been used in a use-after-free that could have resulted in a priviledge escalation to gain ring0 access from the system user (bsc#1207190).

A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e

Описание

A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info` actually points to something else that is potentially controlled by local user. It is known how to trigger this, which causes an out of bounds access, and a lock corruption.

In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device.
