CVE-2026-45958

A flaw was found in the Linux kernel's drm/exynos: vidi driver. A local user could exploit this vulnerability by directly dereferencing a user pointer in the vidiconnectionioctl function. This allows for arbitrary kernel memory access from user space, potentially leading to privilege escalation o...

SUSE CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

CVE-2026-43073

In the Linux kernel, the following vulnerability has been resolved: x86-64: rename misleadingly named 'copyusernocache' function This function was a masterclass in bad naming, for various historical reasons. It claimed to be a non-cached user copy. It is literally neither of those things. It's a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: Do not rely on user vaddr alignment. There is no guaranteed alignment for user pointers. However, the calculation of the offset from the first page to a folio after coalescing uses some strange bit mask logic;...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Fixed a dangling pointer in krbauthenticate. krbauthenticate frees sess-user and does not set the pointer to NULL. It calls ksmbdkrb5authenticate to reinitialise sess-user, but that function may return without doing so...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: scsi: qedi: Fix crash while reading debugfs attribute The qedidbgdonotrecovercmdread function invokes sprintf directly on a user pointer, which results into the crash. To fix this issue, use a small local stack buffer for sprintf...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed a memory leak in kfdmemdmamapuserptr. If the number of pages from the userptr BO differs from the SG BO, then the allocated memory for the SG table does not get freed before returning – leading to an EINVAL erro...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: iommufd: Check for uptr overflow syzkaller discovered that setting up a page with a user VA that exceeds zero can trigger WARNONs, especially when pinuserpages returns 0 due to invalid arguments. This issue prevents the creati...

CVE-2023-54239 iommufd: Check for uptr overflow

In the Linux kernel, the following vulnerability has been resolved: iommufd: Check for uptr overflow syzkaller found that setting up a map with a user VA that wraps past zero can trigger WARNONs, particularly from pinuserpages weirdly returning 0 due to invalid arguments. Prevent creating a pages...
