kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound

A flaw was found in the drm/vmwgfx component of the Linux kernel. An integer overflow vulnerability exists in the vmwshaderdefine function due to improper validation of user-supplied shader window size and offset. When the offset value is close to its maximum, an unsigned addition can wrap around...

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...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fixed a memory leak in vmwmksstataddioctl If the copy of the description string from user space fails, then the page containing the instance descriptor does not get freed before returning -EFAULT, resulting in a memor...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fixed stale file descriptors when a usercopy fails. A failed usercopy of the fencerep object will result in a stale entry in the file descriptor table, as putunusedfd will not release that entry. This allows userland ...
