CVE-2025-21758 ipv6: mcast: add RCU protection to mld_newpack()
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...
CVE-2025-21759
CVE-2025-21759: In the Linux kernel, ipv6 mcast path igmp6_send() could be invoked without RTNL/RCU held, risking use-after-free of the net pointer. The fix extends RCU protection to safely fetch the net pointer and avoid UAF, and replaces sock_alloc_send_skb usage with alloc_skb under RCU protec...

CVE-2025-21756
CVE-2025-21756 affects the Linux kernel vsock subsystem. The issue arises from keeping socket bindings until destruction, preventing correct unbinding during transport reassignment. This leads to a use-after-free in the binding path, observed as a KASAN slab-use-after-free in __vsock_bind and rel...
