Race condition in Linux kernel - CVE-2022-45888

Vulnerability identifier: #VU70503

CSH Severity: Low

CVSS v4: 7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-45888

CWE-ID: CWE-362

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows an attacker to escalate privileges on the system.
