Improper locking in Linux kernel - CVE-2024-57918

Vulnerability identifier: #VU103032

CSH Severity: Low

CVSS v4: 6.8 [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]

CVE-ID: CVE-2024-57918

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 remove_all_phantom_planes_for_stream() function in drivers/gpu/drm/amd/display/dc/dml2/dml2_mall_phantom.c, within the dc_state_add_plane(), dc_state_rem_all_planes_for_stream() and dc_state_rem_all_phantom_planes_for_stream() functions in drivers/gpu/drm/amd/display/dc/core/dc_state.c, within the commit_minimal_transition_based_on_current_context() function in drivers/gpu/drm/amd/display/dc/core/dc.c. A local user can perform a denial of service (DoS) attack.
