CVE-2026-80582

A flaw was found in the Linux kernel's drm/shmemhelper component. This vulnerability arises from insufficient boundary checks when handling large memory pages. An attacker could potentially trigger an attempt to map memory outside its designated area. This improper memory handling could lead to a...

CVE-2026-74641

A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: fixed page mapping when vmareaallocpages uses high-order fallback to order 0. The vmappagesrangenoflush function assumes that its argument pages contains pages with the same page shift. However, since commit...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Maps EFI-reserved memory as encrypted for SEV. Some drivers require memory that is marked as EFI boot services data. To prevent this memory from being reused by the kernel after ExitBootServices, efimemreserve is use...

CVE-2026-72496

A flaw was found in the Linux kernel's RDMA/bnxtre component. When the bnxtqpliballocdpi function attempts to map I/O memory ioremap, it may not properly handle failures. This oversight could lead to system instability or a denial of service DoS condition, as the system might proceed with an...

Linux Distros Unpatched Vulnerability : CVE-2026-74380
