Improper locking in Linux kernel - CVE-2022-48887

Vulnerability identifier: #VU96358

CSH Severity: Low

CVSS v4 BT: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-48887

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the vmw_execbuf_rcache_update(), vmw_execbuf_res_noref_val_add(), vmw_view_res_val_add(), vmw_resource_context_res_add(), vmw_cmd_res_check(), vmw_translate_mob_ptr(), vmw_translate_guest_ptr(), vmw_cmd_set_shader(), vmw_cmd_dx_set_shader(), vmw_cmd_dx_bind_shader(), vmw_cmd_dx_bind_streamoutput(), vmw_cmd_dx_set_streamoutput() and vmw_execbuf_tie_context() functions in drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c, within the vmw_user_bo_lookup() function in drivers/gpu/drm/vmwgfx/vmwgfx_bo.c, within the ttm_base_object_unref() and ttm_base_object_lookup() functions in drivers/gpu/drm/vmwgfx/ttm_object.c. A local user can perform a denial of service (DoS) attack.
