CVE-2021-47091

CVE-2021-47091 affects the Linux kernel mac80211 component. Root cause: locking in ieee80211_start_ap error path where local channel context release wasn’t guaranteed to hold local->mtx, risking improper synchronization. The fix enforces holding local->mtx when releasing the channel context...

CVE-2023-52516

CVE-2023-52516 affects the Linux kernel’s dma-debug path. The root cause is that __dma_entry_alloc_check_leak() could be invoked while holding free_entries_lock and then call printk/serial console while port->lock is held, creating a reverse locking dependency chain: console_owner -> port_l...
