The vulnerability in the function nouveau_drm_probe() of the drivers/gpu/drm/nouveau/nouveau_drm.c file, a driver for the Direct Rendering Infrastructure (DRI) of NVIDIA graphics cards in the Linux operating system, allows a hacker to cause a service failure.

The vulnerability of the nouveaudrmprobe function in the drivers/gpu/drm/nouveau/nouveaudrm.c file of the NVIDIA driver framework for the Direct Rendering Infrastructure DRI of the Nouveau graphics card in the Linux operating system is related to unlimited resource allocation. Exploiting this...

The vulnerabilities of the functions nv50_piorDestroy() and nv50_piorCreate() in the driver/gpu/drm/nouveau/dispnv50/disp.c file of the Nouveau driver for the Direct Rendering Infrastructure (DRI) of NVIDIA’s Linux kernel allow a malicious actor to cause a service failure.

The vulnerability of the functions nv50piordestroy and nv50piorcreate in the drivers/gpu/drm/nouveau/dispnv50/disp.c module of the Nouveau graphics driver for Linux operating systems is related to the lack of resource initialization. Exploiting this vulnerability can allow an attacker to cause a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: nouveau/dmem: Handling of allocation failures by kcalloc In nouveaudmemevictchunk, if the physical memory runs out, kcalloc will return null. As a result, if we dereference srcpfns, dstpfns, or dmaaddrs, null pointer...

Astra Linux – Vulnerability in Linux

A NULL pointer dereference flaw was discovered in the Linux kernel’s GPU Nouveau driver functionality in versions prior to 5.12-rc1. This flaw allows a local user to crash the system. The flaw occurs when the user calls ioctl DRMIOCTLNOUVEAUCHANNELALLOC...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/nouveau: Avoid a use-after-free when BO init fails nouveauboinit is backed by ttmboinit and passes its return value back to the caller. In case of failures, ttmboinit invokes the provided destructor, which should...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/disp: fixed a use-after-free in error handling of nouveauconnectorcreate. We cannot simply free the connector after calling drmconnectorinit on it. We need to clean up the DRM-related aspects first. This may not fix a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/nouveau/kms/nv50-: fixed the file release memory leak. When using singleopen to open a device, singlerelease should be called. Otherwise, the “op” that was allocated in singleopen will be leaked...

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

In the Linux kernel, the following vulnerability has been resolved: drm: nv04: Fix for out-of-bounds access When the value of dcb-or is assigned in fabricatedcboutput, there may be an out-of-bounds access to the dacusers array, especially when dcb-or is zero. This occurs because ffsdcb-or is used...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fixed an issue where the BIOS boundary checking was off by one. Bounds checking during the parsing of init scripts embedded in the BIOS prevents access to the last byte. This causes driver initialization to fail on...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/nouveau/debugfs: fixed the memory leak when releasing files. When using singleopen to open a file, singlerelease should be called. Otherwise, the memory allocated with singleopen may be leaked...
