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 in 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 – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi – fixed an issue to avoid directly dereferencing the user pointer. In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user...

Astra Linux – Vulnerability in 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 – this may lead to a memory...

SUSE CVE-2026-80865

In the Linux kernel, the following vulnerability has been resolved: bpf: Add missing accessok call to copyusersyms As reported by sashiko we use getuser without prior accessok call on the user space pointer. Adding the missing call for the whole pointer array. Plus removing the err check in the...

EUVD-2026-71495

In the Linux kernel, the following vulnerability has been resolved: bpf: Add missing accessok call to copyusersyms As reported by sashiko we use getuser without prior accessok call on the user space pointer. Adding the missing call for the whole pointer array. Plus removing the err check in the...

PT-2026-85784

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue exists in the bpf component where the copy user syms function uses get user on a user space pointer without a preceding access ok call. This missing check fails to verify if th...

CVE-2026-74258

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard getuser acesss with accessok for uprobemulti data As reported by sashiko 1 we need to use accessok to check the user space data bounds before we use get-user to get it. 1...

CVE-2026-12364 Missing user-space pointer validation in logging syscall z_log_msg_static_create allows kernel memory disclosure and denial of service

The user-space system-call verifier zvrfyzlogmsgstaticcreate in subsys/logging/logmsg.c was a pure pass-through: it forwarded the caller-supplied source, desc, package, and data arguments directly to the kernel-mode implementation zimplzlogmsgstaticcreate without performing any of the mandatory...

CVE-2026-68435

A flaw was found in the Linux kernel, specifically within the LoongArch architecture's kexec command line lookup functionality. A local attacker could exploit this by using the kexecload system call, which incorrectly passes a user-space segment buffer to a kernel function without proper...

DEBIAN-CVE-2026-68435

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix address space mismatch in kexec command line lookup When searching the loaded segments for the "kexec" command line marker, the kexecload2 path filemode == 0 passes the user-space segment buffer straight to strncmp...

CVE-2026-68435 LoongArch: Fix address space mismatch in kexec command line lookup

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix address space mismatch in kexec command line lookup When searching the loaded segments for the "kexec" command line marker, the kexecload2 path filemode == 0 passes the user-space segment buffer straight to strncmp...

CVE-2026-68101

CVE-2026-68101 affects the Linux kernel DRM/amdgpu path. The vulnerability arises in amdgpu_hmm_invalidate_gfx where, briefly during alloc/free, the userptr BO is not part of the VM, making bo->vm_bo potentially NULL. The fix keeps a reference to the VM root page directory as the parent of the...

CVE-2026-53201

In the Linux kernel, the following vulnerability has been resolved: Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend" This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6. The idle-skip optimization bypasses GuC suspend, so the GPU may not perform the contex...

CVE-2026-53159

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix DMA address corruption due to findvma misuse fastrpcgetargs uses findvma to look up the VMA for a user-provided pointer and compute a DMA address offset. When the address falls in a gap before the returned VMA,...

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...
