- 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).
