- Summary
- netfilter: nf_conncount: update last_gc only when GC has been performed
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nfconncount: update lastgc only when GC has been performed
Currently last_gc is being updated everytime a new connection is tracked, that means that it is updated even if a GC wasn't performed. With a sufficiently high packet rate, it is possible to always bypass the GC, causing the list to grow infinitely.
Update the last_gc value only when a GC has been actually performed.
