CVE-2023-51779 is a use-after-free vulnerability in the Linux kernel Bluetooth subsystem affecting kernels through 6.6.8. A race between bt_sock_recvmsg() and bt_sock_ioctl() can cause a socket buffer (skb) to be accessed after it has been freed. A local low-privileged user may trigger denial of service or potentially execute code. Exploitation is considered difficult, and local privilege escalation has not been confirmed.
