Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU85023

Risk: Low

CVSSv4.0: 5.9 [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:U/U:Clear]

CVE-ID: CVE-2023-51779

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error when handling bt_sock_ioctl in the Bluetooth subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.

Mitigation

Install updates from vendor's repository.
