Vulnerability from github – Published: 2024-10-21 21:30 – Updated: 2024-10-25 15:31

Details

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.

Severity

5.5 (Medium)
