Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 6.0.11. Affected is the function can327_feed_frame_to_netdev. The manipulation with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down In can327_feed_frame_to_netdev(), it did not free the skb when netdev is down, and all callers of can327_feed_frame_to_netdev() did not free allocated skb too. That would trigger skb leak. Fix it by adding kfree_skb() in can327_feed_frame_to_netdev() when netdev is down. Not tested, just compiled.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2022-49008 since 08/22/2024. The exploitability is told to be difficult. There are known technical details, but no exploit is available.
