Security Bulletin

This security bulletin contains information about 11 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU24446

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19083

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 "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

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3435

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the fib_nh_match() function in net/ipv4/fib_semantics.c IPv4 handler. A remote attacker can send specially crafted data to the system, trigger an out-of-bounds read error and read contents of memory on the system.

8) Input validation error

EUVDB-ID: #VU70468

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3643

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of network packets. An attacker with access to the guest OS can trigger the related physical NIC on the host to reset, abort, or crash by sending certain kinds of packets.

Mitigation

Update the affected package the Linux Kernel to the latest version.
