Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 2 for SLE 15 SP4)
Description of the patch
This update for the Linux Kernel 5.14.21-150400_24_18 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).
