[PATCH OLK-6.6] Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()
by Ziyang Xuan 07 Jun '24

07 Jun '24

From: Sungwoo Kim <iam(a)sung-woo.kim> stable inclusion from stable-v6.6.32 commit cfe560c7050bfb37b0d2491bbe7cd8b59e77fdc5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RMPS CVE: CVE-2024-36013 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4d7b41c0e43995b0e992b9f8903109275744b658 upstream. Extend a critical section to prevent chan from early freeing. Also make the l2cap_connect() return type void. Nothing is using the returned value but it is ugly to return a potentially freed pointer. Making it void will help with backports because earlier kernels did use the return value. Now the compile will break for kernels where this patch is not a complete fix.
