Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-11-03 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: RFCOMM: avoid leaving dangling sk pointer in rfcomm_sock_alloc()

bt_sock_alloc() attaches allocated sk object to the provided sock object. If rfcomm_dlc_alloc() fails, we release the sk object, but leave the dangling pointer in the sock object, which may cause use-after-free.

Fix this by swapping calls to bt_sock_alloc() and rfcomm_dlc_alloc().

Severity ?

7.8 (High)
