Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU104379

Risk: Low

CVSSv4.0: 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-2022-49135

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

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

The vulnerability exists due to memory leak within the dp_link_settings_read(), dp_phy_settings_read(), dp_dsc_clock_en_read(), dp_dsc_slice_width_read(), dp_dsc_slice_height_read(), dp_dsc_bits_per_pixel_read(), dp_dsc_pic_width_read(), dp_dsc_pic_height_read(), dp_dsc_chunk_size_read(), dp_dsc_slice_bpg_offset_read() and dcc_en_bits_read() functions in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c. A local user can perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
