Description
This security bulletin contains information about 1 vulnerability.
1) Return of Wrong Status Code (CVE-ID: CVE-2026-98842)
CWE-ID: CWE-393 - Return of Wrong Status Code
CVSSv4: 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]
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.
