CVE-2026-31551

The CVE-2026-31551 entry relates to the Linux kernel mac80211 wifi subsystem. A race in aql_enable_write() during concurrent debugfs writes can cause a static_branch_dec() underflow because the code checks static_key_false(&aql_disable.key) and then later increments/decrements the static branch, ...
