- Summary
- can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
can: can327: can327feedframetonetdev(): fix potential skb leak when netdev is down
In can327feedframetonetdev(), it did not free the skb when netdev is down, and all callers of can327feedframetonetdev() did not free allocated skb too. That would trigger skb leak.
Fix it by adding kfreeskb() in can327feedframeto_netdev() when netdev is down. Not tested, just compiled.
