CVE-2023-52581 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix memleak when more than 255 elements expired
When more than 255 elements expired we're supposed to switch to a new gc container structure.
This never happens: u8 type will wrap before reaching the boundary and nft_trans_gc_space() always returns true.
This means we recycle the initial gc container structure and lose track of the elements that came before.
While at it, don't deref 'gc' after we've passed it to call_rcu.
