Security Bulletin
This security bulletin contains one high risk vulnerability.
1) Use-after-free
EUVDB-ID: #VU71482
Risk: High
CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]
CVE-ID: CVE-2023-0266
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the snd_ctl_elem_read() function in the Linux kernel sound subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.
Note, the vulnerability is being actively exploited in the wild.
Install updates from vendor's repository.
