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...
Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, Linux, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: In the xskmapdeleteelem function, an unsigned integer map-maxentries is compared with a user-controlled signed integer k. Due to implicit type conversion, a large unsigned value for map-maxEntries can bypass the intended bounds...
CVE-2026-74709
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-2026-74708
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-2026-74707
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-2026-64397
In the Linux kernel, the following vulnerability has been resolved: xsk: require at least 16 bytes of TX metadata AFXDP accepts a TX metadata length as small as eight bytes, but every supported request needs the flags plus at least one eight-byte request field. Such short metadata also lets the...
CVE-2026-74710 xsk: require at least 16 bytes of TX metadata
In the Linux kernel, the following vulnerability has been resolved: xsk: require at least 16 bytes of TX metadata AFXDP accepts a TX metadata length as small as eight bytes, but every supported request needs the flags plus at least one eight-byte request field. Such short metadata also lets the...

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...

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...
