14) Use-after-free

EUVDB-ID: #VU68423

Risk: Low

CVSSv4.0: 6.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2022-2602

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free error caused by an io_uring request, which is being processed on a registered file. The Unix GC runs and frees the io_uring file descriptor and all the registered file descriptors in a specific order that may allow a local user to win a race and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.
