CVE-2026-72322

CVE-2026-72322 concerns a race in the Linux kernel IPv6 multicast code (MLD delayed work) that can cause a Use-After-Free during device teardown and MLD query processing. The root cause is a use of in6_dev_hold() to take a reference on inet6_dev while it may already be freed (RCU-protected memory...

CVE-2026-72250

The CVE-2026-72250 entry documents a Linux kernel vulnerability in netfilter nf_conntrack_reasm where IPv6 defragmentation erroneously adjusts skb->mac_header. Specifically, nf_ct_frag6_reasm() advances skb->mac_header after dropping the IPv6 fragment header, but on NF_INET_LOCAL_OUT the ma...

CVE-2026-72021

Summary: The CVE-2026-72021 issue affects the Linux kernel’s IPVS SCTP state lookup. The kernel incorrectly read the SCTP chunk header using a wrong offset for IPv6 when extension headers were present, causing misclassification of handshake steps (e.g., INIT1 vs ESTABLISHED) and incorrect managem...

CVE-2026-68477 ipvs: fix more places with wrong ipv6 transport offsets

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix more places with wrong ipv6 transport offsets Sashiko reports for more incorrect IPv6 transport offsets. The app code for TCP was assuming IPv4 network header even after the ipvsh argument was provided. This can cause...

CVE-2026-68477

CVE-2026-68477 relates to the Linux kernel IPVS handling of IPv6 transport offsets. The vulnerability stems from code paths that continued to assume an IPv4 network header after the ipv6 switch, causing incorrect IPv6 transport offset handling for TCP and related paths, and potentially impacting ...
