| Doc Text: |
A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nft_verdict_init() function, allowing positive values as a drop error within the hook verdict, therefore, the nf_hook_slow() function can cause a double-free vulnerability when NF_DROP is issued with a drop error that resembles NF_ACCEPT. The nf_tables component can be exploited to achieve local privilege escalation.

I wonder if this maybe slipped through the cracks, and actually delays fixing the issue for 9.3/9.4? And even if not, it's something to fix on that access page. Thanks! > https://access.redhat.com/security/cve/CVE-2024-1086 does not mention RHEL 9 latest at all
Oops, I was wrong, sorry! It does say RHEL 9 is Affected on the second page of results (the first page is "1-10 of 12"). I find this UI non-intuitive, and keep forgetting more pages of results may exist. Anyway, good to know the issue is known and acknowledged.
