Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU69795

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-42896

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the l2cap_connect() and l2cap_le_connect_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can trigger a use-after-free error and execute arbitrary code on the system.


Mitigation

Install updates from vendor's repository.

2) Use-after-free

EUVDB-ID: #VU74122

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-2023-1281

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 in Linux kernel traffic control index filter (tcindex) when the tcf_exts_exec() function is called with the destroyed tcf_ext. A local user attacker can trigger a use-after-free error and execute arbitrary code with elevated privileges.


Mitigation
