CVE-2023-40283

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.4.10

Description The issue is related to the l2cap sock release function in the Linux kernel, specifically in the net/bluetooth/l2cap sock.c file. It involves a use-after-free error because the children of an sk are mishandled. This could potentially allow an attacker to cause a denial of service or have other impacts.

Recommendations For Linux kernel versions prior to 6.4.10, update to version 6.4.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the l2cap sock release function in net/bluetooth/l2cap sock.c until a patch is available.
