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...

CVE-2026-43319

CVE-2026-43319 affects the Linux kernel spidev driver. The vulnerability stemmed from inverted lock ordering between spi_lock and buf_lock across code paths (write/read use buf_lock then spi_lock; ioctl uses spi_lock then buf_lock), enabling potential deadlocks in multi-threaded access. The fix u...
