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 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Do not treat wbconnector as a physical device in createvalidatestreamforsink. Do not attempt to operate on drmwbconnector as an amdgpudmconnector. While dereferencing connector-base may “work”, it is incorrect an...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/sched: Increasing the job count before swapping the SPSC queue. There is a minor race condition between spscqueuepush and the run-job worker. In this race condition, spscqueuepush may return not-first, while the run-job worke...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix slab-use-after-free in hdcp The HDCP code in amdgpudmhdcp.c copies pointers to amdgpudmconnector objects without incrementing the kref reference counts.

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dsi: Added a missing check for allocorderedworkqueue. Added a check on the return value of allocorderedworkqueue, as it may return a NULL pointer, leading to a NULL pointer dereferencing issue. Patchwork:...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for a potential null return from kmallocarray. Since kmallocarray may return null, the use of 'eventwaitersi.wait' could lead to a null pointer derefrence. Therefore, it is better to check the return value of...

kernel: drm/xe: Open-code GGTT MMIO access protection

A flaw was found in the drm/xe component of the Linux kernel. This vulnerability involves insufficient protection of Graphics Translation Table GGTT Memory-Mapped I/O MMIO access. When the driver fails to load or during certain cleanup operations, the system's memory access protection is...

kernel: drm/xe: always keep track of remap prev/next

A flaw was found in the Linux kernel's drm/xe driver. During 3D workload processing, a user process can trigger an issue in the Virtual Memory Area VMA management when performing a rebind operation. This can lead to an invalid or overlapping VMA insertion, causing the system to enter an unstable...

kernel: drm/i915: Fix potential overflow of shmem scatterlist length

A flaw was found in the Linux kernel's graphics memory management drm/i915 component. This vulnerability occurs when a large shared memory object's internal list of memory segments, called a scatterlist, is populated. If the total size of these segments exceeds 4 Gigabytes GB, a numerical overflo...

kernel: drm/xe/pt: Reset current_op in xe_pt_update_ops_init()

A flaw was found in the Linux kernel's drm/xe/pt module. During certain memory management operations, an internal counter is not properly reset. Repeated attempts to perform these operations, possibly due to resource contention or out-of-memory conditions, can cause this counter to exceed its...
