CVE-2026-74709

A flaw was found in the Linux kernel's xsk AFXDP sockets component. A local attacker, by manipulating metadata flags after request processing, could cause the kernel to write a timestamp into the metadata area even when not explicitly requested. This could lead to unintended data modification...

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-2026-74709

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...

iOS/macOS - Out-of-Bounds Timestamp Write in IOAccelCommandQueue2::processSegmentKernelCommand()

While investigating possible shared memory issues in AGXCommandQueue::processSegmentKernelCommand, I noticed that the size checks used to parse the IOAccelKernelCommand in IOAccelCommandQueue2::processSegmentKernelCommand are incorrect. The IOAccelKernelCommand contains an 8-byte header consistin...
