Use-after-free in Linux kernel - CVE-2022-29582

Vulnerability identifier: #VU63792

CSH Severity: Low

CVSS v4: 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]

CVE-ID: CVE-2022-29582

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to a use-after-free error in the io_uring timeouts() function in the Linux kernel. A local user can trigger a race condition between timeout flush and removal to cause a denial of service or escalate privileges on the system.
