CVE-2026-31551

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the mac80211 wifi component where the aql enable write() function does not serialize concurrent writes to the debugfs. This can lead to a static branch dec() underflow for aql disable because the state may change between the call to static key false(&aql disable.key) and the subsequent call to static branch inc() or static branch dec().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
