Improper Resource Shutdown or Release in Linux kernel - CVE-2025-71268

Vulnerability identifier: #VU124202

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2025-71268

CWE-ID: CWE-404

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a resource management error in the Btrfs filesystem component when handling qgroup data during inline extent insertion. A local user can trigger a reservation leak in error paths to cause a denial of service.

The vulnerability specifically occurs if allocation of a path or transaction join fails, leading to unfreed qgroup reservations. This results in gradual resource exhaustion over time.
