Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the thunderbolt component where the tb xdp handle request function casts a received packet buffer to protocol-specific structs without verifying if the allocation is...

EUVD-2026-38905

In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix deadlock in hidpostreset You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hidprereset and hidpostreset are in the...

In the Linux kernel, the following vulnerability has been resolved: bpf: Validate nodeid in arenaallocpages arenaallocpages accepts a plain int nodeid and forwards it through the entire allocation chain without any bounds checking. Validate nodeid before passing it down the allocation chain in...

CVE-2026-53059

In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to regioncount overflow The local variable regioncount in createlogcontext is declared as unsigned int 32-bit, but dmsectordivup returns sectort 64-bit. When a device-mapper target has a...

CVE-2026-52959

In the Linux kernel, the following vulnerability has been resolved: virt: sev-guest: Do not use host-controlled page order in cleanup path When issuing an extended guest request SVMVMGEXITEXTGUESTREQUEST, getextreport allocates a buffer to retrieve a certificate blob from the host, keeping track ...

CVE-2026-53059 dm log: fix out-of-bounds write due to region_count overflow

In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to regioncount overflow The local variable regioncount in createlogcontext is declared as unsigned int 32-bit, but dmsectordivup returns sectort 64-bit. When a device-mapper target has a...

CVE-2026-53037

CVE-2026-53037 affects the Linux kernel with a deadlock in HID reset handling when a USB HID device is paired with a storage/UAS component. The issue arises because hid_pre_reset() and hid_post_reset() may perform memory allocations that touch IO, risking deadlock, so the patch switches allocatio...

CVE-2026-52922

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: udptunnel: Use netdevwarn instead of netdevWARN. netdevWARN uses WARN/WARNON to print a backtrace along with file and line information. In this case, udptunnelnicregister failing due to a memory allocation failure e.g., kzalloc o...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Set numsyncs to a limit to prevent excessively large allocations. The exec and vmbind ioctls allow userspace to specify an arbitrary value for numsyncs. Without bounds checking, a very large value of numsyncs can result i...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, there was a vulnerability where a memory allocation failure in the sixel encoder could lead to writing beyond the end of a buffer on the stack. This vulnerability...
