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

A race condition was detected in the Linux kernel’s DRM/Exynos device driver, specifically in the exynosdrmcrtcatomicdisable function. This can lead to a null pointer dereferencing issue, which may potentially cause a kernel panic or a denial of service condition...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fixed memory leakage This patch addresses potential memory leakage and segmentation faults in the gpuvmimportdmabuf function...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Install a stub fence into potential unused fence pointers. When using cpu to update page tables, VM update fences are unused. Install a stub fence into these fence pointers instead of using NULL. This prevents NULL...

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

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: cdns-mhdp8546: Fixed possible null pointer dereferencing In cdnsmhdpatomicenable, the return value from drmmodeduplicate is assigned to mhdpstate-currentmode. There is a situation where mhdpstate-currentmode is...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm: Fixed a potential null-ptr-deref due to drmmmodeconfiginit. drmmmodeconfiginit will call drmmodecreatestandardproperties, and it does not check the return value. When drmmodecreatestandardproperties fails due to allocatio...

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/exynos: exynos7drmdecon: added a check for virtual blinking vblank during IRQ handling. If there is support for another console device such as a TTY serial, the kernel occasionally panics during boot. The panic message and a...

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/vmwgfx: Validating the command header size against SVGACMDMAXDATASIZE This data originates from user space and is used in buffer offset calculations, which may potentially lead to an out-of-bounds access due to overflow...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: drm/msm: Another leak in the submit error path has been fixed. putunusedfd does not free the allocated file if we have already performed fdinstall. Therefore, we also need to free the syncfile. Patchwork:...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/dpmst: Ensure that the mstprimary pointer is valid in drmdpmsthandleupreq. While receiving an MST up request message from one thread in drmdpmsthandleupreq, the MST topology might be removed by another thread via...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel before version 6.0.3, the file drivers/gpu/drm/virtio/virtgpuobject.c misinterprets the return value of drmgemshmemgetsgtable. It expects the value to be NULL in the error case, but in reality, it is an error pointer...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: The return error code in mdp5mixerrelease is incorrect when a deadlock is detected. There is a possibility that mdp5getglobalstate may return-EDEADLK when acquiring the modeset lock. However, currently,...

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

In the Linux kernel, the following vulnerability has been resolved: drm/qxl: Added a check for drmcvtmode. Added a check on the return value of drmcvtmode, and return an error if it fails, in order to avoid NULL pointer dereferencing...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Assign the job pointer to NULL before signaling the fence In commit e4b5ccd392b9 “drm/v3d: Ensure the job pointer is set to NULL after the job completes”, we introduced a change to assign the job pointer to NULL after...

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

In the Linux kernel before version 6.4.5, the file driver/gpu/drm/drmatomic.c contained a use-after-free during a race condition between a nonblocking atomic commit and a driver unloading process...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm: fixed NULL dereferencing during snapshot cleanup. In cases of early initialization errors, and on platforms that do not use the DPU controller, the deinitialization code can be called with the kms pointer set to NULL...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: drm: bridge/panel: The cleanup of the connector occurs when the bridge is detached. If we do not call drmconnectorcleanup manually in panelbridgedetach, the connector will be cleaned up along with other DRM objects during the cal...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix for a use-after-free bug This bug can be triggered by sending a single amdgpugemuserptrioctl command to the AMDGPU DRM driver on any ASICs with an invalid address and size. The bug was reported by Joonkyo Jung . F...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Do not access invalid sched. Since 2320c9e6a768 “drm/sched: memset ‘job’ in drmschedjobinit”, accessing job-base.sched can produce unexpected results, as the initialization of job-base.sched during amdgpujoballoc is...
