7) Use-after-free

EUVDB-ID: #VU78066

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3389

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 in the Linux Kernel io_uring subsystem. A local user can exploit a race condition and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.
