Return of Wrong Status Code in Linux kernel - CVE-2026-98842

Vulnerability identifier: #VU157210

CSH Severity: Low

CVSS v4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-98842

CWE-ID: CWE-393

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local privileged user to cause failed kernel module loads to be reported as successful.

The vulnerability exists due to incorrect error propagation in the Linux kernel load_module() function when codetag_load_module() fails. A local privileged user can initiate a module load that encounters this failure to cause load_module() to return a success status even though the module has been torn down.
