Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU66591

Risk: Low

CVSSv4.0: 4.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-1462

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the the Linux kernel’s TeleTYpe subsystem caused by a race condition when using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory file. A local user can trigger an out-of-bounds read error and crash the system or read random kernel memory.

Mitigation

Install updates from vendor's repository.

2) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU66810

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-2503

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way dm-verity is used to restrict module/firmware loads to trusted root filesystem in LoadPin builds. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.

Mitigation

Install updates from vendor's repository.

CVE-ID: CVE-2022-2959

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a missing lock in the pipe_resize_ring() function within the watch queue when performing operations on an object. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
