SUSE CVE-2025-21758

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: add RCU protection to mldnewpack mldnewpack can be called without RTNL or RCU being held. Note that we no longer can use sockallocsendskb because ipv6.igmpsk uses GFPKERNEL allocations which can sleep. Instead use...

SUSE CVE-2025-21759

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: extend RCU protection in igmp6send igmp6send can be called without RTNL or RCU being held. Extend RCU protection so that we can safely fetch the net pointer and avoid a potential UAF. Note that we no longer can use...
