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-2026-74709 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...

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...

CVE-2026-68418 RDMA/irdma: Prevent user-triggered null deref on QP create

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent user-triggered null deref on QP create Previously, the user QP creation path would only attempt to populate iwqp-iwpbl if the user-provided req.userwqebufs field was non-zero. The problem is that iwqp-iwpbl is...

EUVD-2026-55363

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix user array stride in pvrsetuobjarray pvrsetuobjarray copies an array of kernel objects to a userspace array whose element size is described by out-stride. When out-stride is different from the kernel object...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: reset: gpio: Suppressing the bind attributes in sysfs. This is a special device that is created dynamically and is supposed to remain in memory forever. Currently, there is no devlink between this device and the actual reset...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: smscufx – The data passed through ioctl is copied to the kernel’s space properly. The UFXIOCTLREPORTDAMAGE ioctl does not copy data from user space to the kernel’s space properly. Instead, it directly references the memory...

CVE-2026-64559 s390/pkey: Check length in PKEY_VERIFYPROTK ioctl

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in PKEYVERIFYPROTK ioctl Explicitly check the buffer length request structure provided by user-space and fail, if it exceeds the buffer size...

CVE-2024-14040

CVE-2024-14040 affects the Linux kernel’s nexthop handling in ECMP/CLOS networks. The patch increases the nexthop weight width from 8-bit to 16-bit to accommodate large weight ratios (e.g., 1000:999) that don’t fit in 8 bits. The UAPI changes introduce a weight_high field and split fields to pres...

CVE-2026-64449

CVE-2026-64449 relates to the Linux kernel staging/vme_user code. The vulnerability arises because the SLAVE-path helpers buffer_to_user() and buffer_from_user() copy count bytes using an unsafe offset (*ppos) into a fixed-size kern_buf (128 KiB), without bounding *ppos + count against size_buf. ...

CVE-2026-10677 Kernel heap memory leak in `z_vrfy_k_poll()` lets an unprivileged user thread exhaust the kernel resource pool
