CVSSv3.1: 5.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3268

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

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the relay_file_read_start_pos() function in kernel/relay.c in the relayfs. A local user can trigger an out-of-bounds read error and read contents of memory on the system or crash the kernel.

Mitigation

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