Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU74124

Risk: Low

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

CVE-ID: CVE-2023-1074

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a local user to perform DoS attack on the target system.

The vulnerability exists due memory leak in Linux kernel Stream Control Transmission Protocol. A local user can start a malicious network service and then connect to remotely, forcing the kernel to leak memory.

Mitigation

Install updates from vendor's repository.
