Vulnerability from github – Published: 2024-04-28 15:30 – Updated: 2025-01-07 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain()

It seems to me that percpu memory for chain stats started leaking since commit 3bc158f8d0330f0a ("netfilter: nf_tables: map basechain priority to hardware priority") when nft_chain_offload_priority() returned an error.

Severity ?

5.5 (Medium)
