Improper control of a resource through its lifetime in Linux kernel - CVE-2026-90357

Vulnerability identifier: #VU151129

CSH Severity: Low

CVSS v4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90357

CWE-ID: CWE-664

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to corrupt kernel driver state.

The vulnerability exists due to improper resource lifecycle management in the mt7915 TWT flow list when handling a TWT agreement rejected by the MCU. A local user can trigger a rejected TWT agreement to corrupt kernel driver state.

A reused flow slot can remain linked in the TWT list, leaving a dangling entry that is later traversed.
