Vulnerability identifier: #VU123224

CSH Severity: Low

CVSS v4: 2.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-27799

CWE-ID: CWE-122

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
