Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel (Operating System) (affected version not known). Affected is the function vmw_execbuf_tie_context of the file drivers/gpu/vmxgfx/vmxgfx_execbuf.c of the component vmwgfx Driver. The manipulation with an unknown input leads to a use after free vulnerability. CWE is classifying the issue as CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. This is going to have an impact on availability. CVE summarizes:

A use-after-free(UAF) vulnerability was found in function 'vmw_execbuf_tie_context' in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in Linux kernel's vmwgfx driver with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).

The weakness was disclosed 09/09/2022 as 2075. The advisory is available at bugzilla.openanolis.cn. This vulnerability is traded as CVE-2022-40133 since 09/07/2022.
