Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU75451

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-1855

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the xgene_hwmon_remove() function in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). A local user can trigger a use-after-free error and execute arbitrary code on the system.

Mitigation

Install updates from vendor's repository.

4) Race condition

EUVDB-ID: #VU75104

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-2006

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 race condition within the processing of RxRPC bundles in net/rxrpc/ar-internal.h. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.

Mitigation
