Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU22741

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-17052

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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

The vulnerability exists due to the ax25_create() function in net/ax25/af_ax25.c in the AF_AX25 network module for the Linux kernel does not enforce CAP_NET_RAW when creating raw sockets. A local unprivileged user can create raw sockets on the system.

Mitigation
