1) Out-of-bounds read

EUVDB-ID: #VU67473

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-2022-20368

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the packet_recvmsg() function in Linux kernel. A local user can trigger an out-of-bounds read error and potentially escalate privileges on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
