CVE-2026-53111

CVE-2026-53111 is a Linux kernel issue where bpf_lwt_xmit_push_encap dereferences skb_dst(skb)->dev during test_run when skb->_skb_refdst is uninitialized, leading to a kernel crash. A patch and remediation include initializing skb->_skb_refdst before bpf_test_run_skb, as evidenced by Ro...

CVE-2026-52961

The CVE-2026-52961 entry describes a race in the Linux kernel Ceph xattr handling. Root cause: during __build_xattrs_blob(), the required_blob_size computation happens before __build_xattrs(), while __build_xattrs() may release and reacquire i_ceph_lock, allowing a newer MDS-provided blob to repl...
