CVE-2026-74710

CVE-2026-74710 is an out-of-bounds read in the Linux kernel's AF_XDP (xsk) component. The mechanism accepts a TX metadata length as small as eight bytes, but every supported request requires the flags field plus at least one eight-byte request field (16 bytes minimum). When metadata shorter than ...

CVE-2026-74709 xsk: clear metadata pointer when no timestamp is requested

In the Linux kernel, the following vulnerability has been resolved: xsk: clear metadata pointer when no timestamp is requested User space can change metadata flags after request processing. Rereading them during completion can therefore make the kernel write a timestamp that was not requested whe...

CVE-2026-74709

CVE-2026-74709 affects the AF_XDP (xsk) subsystem in the Linux kernel. The root cause is that user space can modify metadata flags after a TX request has been processed; when the kernel rereads those flags during completion, it may write a timestamp into the metadata area that was never requested...

CVE-2026-74707

CVE-2026-74707 affects the Linux kernel's xsk (AF_XDP sockets) component, specifically the zero-copy TX path . The root cause is a time-of-check-to-time-of-use (TOCTOU) flaw: TX metadata is validated when obtaining the descriptor context but then read again later when preparing the hardware reque...

EUVD-2026-64394

In the Linux kernel, the following vulnerability has been resolved: xsk: validate metadata when processing requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it again later when preparing the hardware request. User space can change the metadata...

EUVD-2026-64395

In the Linux kernel, the following vulnerability has been resolved: xsk: validate launch-time metadata size Launch-time metadata extends beyond the first 16 bytes of struct xsktxmetadata. Reject the request when the registered metadata area does not contain the complete field. Snapshot the...

CVE-2026-74708 xsk: validate launch-time metadata size

In the Linux kernel, the following vulnerability has been resolved: xsk: validate launch-time metadata size Launch-time metadata extends beyond the first 16 bytes of struct xsktxmetadata. Reject the request when the registered metadata area does not contain the complete field. Snapshot the...

CVE-2026-74708

CVE-2026-74708 is a Linux kernel vulnerability in the AF_XDP (xsk) subsystem. Launch-time metadata extends beyond the first 16 bytes of struct xsk_tx_metadata, and the kernel failed to validate that the registered metadata area contained the complete field. The fix rejects the request when the me...

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-2026-74597 ip6_tunnel: clear skb2->cb[] in ip6ip6_err()

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip6ip6err ip6ip6err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6send. The clone still carries the outer packet's inet6skbparm in...

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip6ip6err ip6ip6err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6send. The clone still carries the outer packet's inet6skbparm in...

CVE-2026-74597

This vulnerability affects the Linux kernel 's ip6_tunnel module, specifically the ip6ip6_err() function. When processing an outer IPv6 ICMP error packet, the function clones and pulls the skb to the quoted inner IPv6 packet but fails to clear skb2->cb[], leaving the outer packet's inet6_skb_p...
