Comment 6 Hangbin Liu 2024-03-14 03:44:09 UTC 
Hi Zack, Mauro,

RHEL8 and RHEL9 should not be affected as we don't have the fix commit bb7403655b3c ("ipmr: support IP_PKTINFO on cache report IGMP msg"). The skb dst is set correctly before frowarding.
Comment 9 Alex 2024-06-09 13:01:53 UTC 
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26626 is: 	SKIP	The Fixes patch not applied yet, so unlikely that actual: bb7403655b3c3eb245d0ee330047cd3e20b3c4af	YES			NO	NO	unknown (where first YES/NO value means if related sources built).
