CVE-2024-27390 (GCVE-0-2024-27390)

Vulnerability from cvelistv5 – Published: 2024-05-01 13:05 – Updated: 2025-05-04 09:03

Summary
In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: remove one synchronize_net() barrier in ipv6_mc_down() As discussed in the past (commit 2d3916f31891 ("ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()")) I think the synchronize_net() call in ipv6_mc_down() is not needed. Under load, synchronize_net() can last between 200 usec and 5 ms. KASAN seems to agree as well.
Severity ?
No CVSS data available.
