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

A NULL pointer dereference vulnerability was discovered in the vmwgfx driver, located in the file vmwgfxexecbuf.c within the GPU component of the Linux kernel. The vulnerability affects device files such as '/dev/dri/renderD128' or 'Dxxx'. This flaw allows a local attacker with a user account on...

kernel: vmwgfx: integer overflow in vmwgfx_execbuf.c

An integer overflow was found in the Linux kernel's vmwgfx driver. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, and able to issue an ioctl on the resulting file descriptor to crash the system, causing a denial of service...

kernel: failing usercopy allows for use-after-free exploitation

A use-after-free flaw was found in the Linux kernel’s vmwexecbufcopyfenceuser function in drivers/gpu/drm/vmwgfx/vmwgfxexecbuf.c in vmwgfx. This flaw allows a local attacker with user privileges to cause a privilege escalation problem...
