CVE-2026-74535
CVE-2026-74535 affects the Linux kernel Bluetooth ISO subsystem. The vulnerability arises in iso_sock_timeout, which takes lock_sock; keeping the timer disabled while holding that lock may deadlock, and it can run concurrently with iso_conn_del(), leading to a use-after-free of hcon.iso_data. The...
