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, ...

CVE-2022-50091 locking/csd_lock: Change csdlock_debug from early_param to __setup

In the Linux kernel, the following vulnerability has been resolved: locking/csdlock: Change csdlockdebug from earlyparam to setup The csdlockdebug kernel-boot parameter is parsed by the earlyparam function csdlockdebug. If set, csdlockdebug invokes staticbranchenable to enable csdlockwait feature...
