GHSA-3MH8-97G4-P2MV

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-05-07 15:31

Details

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

netfilter: nf_tables: release flow rule object from commit path

No need to postpone this to the commit release path, since no packets are walking over this object, this is accessed from control plane only. This helped uncovered UAF triggered by races with the netlink notifier.

Severity ?

7.0 (High)
