Improper Control of Dynamically-Managed Code Resources in Linux kernel - CVE-2022-25265

Vulnerability identifier: #VU76191

CSH Severity: Low

CVSS v4: 8.5 [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]

CVE-ID: CVE-2022-25265

CWE-ID: CWE-913

Exploitation vector: Local access

Exploit availability: Public exploit is available

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

The vulnerability exists due to an error in Linux kernel due to certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file.
