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.

3) Buffer overflow

EUVDB-ID: #VU83381

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2023-45871

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c when handling frames larger than the MTU. A remote attacker can send specially crafted traffic to the system, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's repository.
