CVE-2026-43332

In the Linux kernel thermal subsystem, CVE-2026-43332 affects the thermal_zone_device_register_with_trips() error path. The root cause is a missing wait_for_completion() after registering a thermal zone device, which can allow the thermal zone object to be freed prematurely if user space holds a ...

CVE-2026-43326

The CVE-2026-43326 entry documents a Linux kernel sched_ext deadlock vulnerability (SCX_KICK_WAIT) where CPUs busy-waited in kick_cpus_irq_workfn() and could form a cycle, freezing the system. The fix defers the wait to a balance callback by replacing the busy-wait with resched_curr(), forcing th...
