Improper resource shutdown or release in Linux kernel - CVE-2026-72425

Vulnerability identifier: #VU143012

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-2026-72425

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 improper resource shutdown or release in ice_reset_all_vfs() when resetting virtual functions with FDIR filters enabled. A local user can trigger a VF reset after enabling an FDIR filter to cause a denial of service.

The issue occurs because CTRL VSI objects are invalidated but not freed for affected virtual functions.
