Memory leak in Linux kernel - CVE-2019-19083

Vulnerability identifier: #VU24446

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-2019-19083

CWE-ID: CWE-401

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 memory leak within the "clock_source_create()" functions under drivers/gpu/drm/amd/display/dc in the Linux kernel before 5.3.8 allow a local user to cause a denial of service (memory consumption).

This vulnerability affects the following functions:

• dce112_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c
  

• dce100_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c
  

• dcn10_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c

• dcn20_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c
  

• dce120_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c
  

• dce110_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c
  

• dce80_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce80/dce80_resource.c
