CVE-2026-74671

CVE-2026-74671 is an out-of-bounds read in the Linux kernel's IMA (Integrity Measurement Architecture) subsystem, specifically in the xattr_verify() function. The root cause is a type mismatch between int and size_t in the digest-length check: sizeof() promotes the entire left-hand expression to ...

CVE-2026-74670

CVE-2026-74670 affects the Linux kernel IPVS (IP Virtual Server) estimator subsystem. The IPVS estimator kthread starts with zeroed chain and tick limits until its initial calculation phase completes. If a network namespace teardown clears ipvs->enable during that phase, ip_vs_est_calc_phase()...

CVE-2026-74669

CVE-2026-74669 affects the Linux kernel IPVS component. When ip_vs_in_icmp() rebases an skb from an outer ICMP packet to the quoted original request, the IPCB(skb)->opt field still describes the outer IPv4 header. A timestamp option in that outer header can leave a stale offset pointing into t...

CVE-2026-74667

CVE-2026-74667 is an out-of-bounds read in the Linux kernel's net/packet subsystem. The packet_parse_headers() function fails to reset skb->mac_header for protocol-bound SOCK_RAW sockets, SOCK_DGRAM frames, and the legacy SOCK_PACKET path. When these frames traverse the PACKET_QDISC_BYPASS tra...
