Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU69758

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-2022-3545

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the area_cache_get() function in drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package linux-oem-5.17 to the latest version.

2) Access of Uninitialized Pointer

EUVDB-ID: #VU69796

Risk: Low

CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-42895

CWE-ID: CWE-824 - Access of Uninitialized Pointer

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists due to unauthorized access of uninitialized pointer within the l2cap_parse_conf_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can gain access to sensitive information.

Mitigation

Update the affected package linux-oem-5.17 to the latest version.
