CVE-2026-90086 xsk: honor XDP_TX_METADATA in zero-copy path

In the Linux kernel, the following vulnerability has been resolved: xsk: honor XDPTXMETADATA in zero-copy path The zero-copy path reads TX metadata whenever the UMEM has metadata space, even if the descriptor does not set XDPTXMETADATA. Pass descriptor options through the metadata helpers and...

CVE-2026-74710

A flaw was found in the Linux kernel's AFXDP eXpress Data Path component. This vulnerability arises because the AFXDP mechanism accepts a transmit TX metadata length that is smaller than required, allowing the kernel to read beyond its designated memory area. An attacker could potentially exploit...

CVE-2026-74707

A flaw was found in the Linux kernel's xsk AFXDP sockets component. This vulnerability allows a local user to bypass security validation by modifying transmission TX metadata after it has been initially checked but before it is used to prepare hardware requests. This could lead to unexpected syst...
