CVE-2026-74612

CVE-2026-74612 is a Linux kernel vulnerability in the veth (virtual Ethernet) driver. When an XDP program adjusts the fragment area, veth_xdp_rcv_skb() updates skb->data_len but leaves skb->len stale, causing skb_headlen() to exceed the actual linear area after a fragment shrink. In the UDP...

CVE-2026-74603

CVE-2026-74603 is a buffer over-read in the Linux kernel's ptp: ocp (Open Compute Project PTP) driver. The EEPROM board ID is a fixed 13-byte field not guaranteed to contain a NUL terminator. Passing it directly to devlink_info_version_fixed_put() treats it as a C string, potentially reading beyo...

CVE-2026-74598

CVE-2026-74598 is an off-by-one length validation error in the Linux kernel's rt6_route_rcv() function, which processes IPv6 Route Information options (RFC 4191) from Router Advertisements. The code accepts length >= 2 and length >= 1 where the RFC requires stricter minimums, causing ipv6_a...
