CVE-2024-56604

Summary (CVE-2024-56604): In the Linux kernel, Bluetooth RFCOMM can leave a dangling sk pointer in rfcomm_sock_alloc() when rfcomm_dlc_alloc() fails, leading to a use-after-free. The root cause is bt_sock_alloc() attaching the sk to the sock object and the code path not clearing the pointer on fa...
