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 if the calculation...

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

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Validated the box size for the snooped cursor. Invalid user-space DMA surface copies could potentially cause an overflow when copying data from the surface to the snooped image, leading to crashes. To address this...

CVE-2026-80702

A flaw was found in the Linux kernel's drm/vmwgfx component. Incorrect assignments of boolean values to the guestmemorysize field instead of the guestmemorydirty bitfield can lead to the field holding an incorrect size. This can cause subsequent operations to read or write past the intended memor...

CVE-2026-80701

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker with DRM master privileges could exploit this by providing oversized cursor dimensions through the DRMIOCTLMODECURSOR2 interface. This improper input validation can lead to a kernel crash, resulting in a Denial of Servi...

CVE-2026-80700

A flaw was found in the drm/vmwgfx component of the Linux kernel. This vulnerability allows a local attacker to cause memory corruption by providing specially crafted input to the vmwexternalbocopy function. The function, which handles copying data between graphics buffers, does not properly...
