CVE-2026-63946 Bluetooth: ISO: fix UAF in iso_recv_frame

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix UAF in isorecvframe isorecvframe reads conn-sk under isoconnlock but releases the lock before using sk, with no reference held. A concurrent isosockkill can free sk in that window, causing use-after-free on...

CVE-2026-63946

CVE-2026-63946: In the Linux kernel Bluetooth ISO path, iso_recv_frame can use a freed sk due to holding iso_conn_lock but releasing it before using conn->sk. The fix replaces a bare pointer read with iso_sock_hold(conn), which holds the sock while the spinlock is still held and atomically inc...
