CVE-2026-72020

CVE-2026-72020 affects the Linux kernel IP Virtual Server (IPVS) code. A bug in ip_vs_conn_new() caused only two ip_vs_seq members (in_seq and out_seq) to be reset, leaving init_seq and previous_delta uninitialized. For connections learned from a sync message, flags and data could be inconsistent...

CVE-2026-72020 ipvs: reset full ip_vs_seq structs in ip_vs_conn_new

In the Linux kernel, the following vulnerability has been resolved: ipvs: reset full ipvsseq structs in ipvsconnnew Commit 9a05475cebdd "ipvs: avoid kmemcachezalloc in ipvsconnnew" changed ipvsconnnew to allocate an ipvsconn object with kmemcachealloc. The function then initializes many fields...

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 ...
