CVE-2026-98909 in Linux
Riassunto
di MITRE • 23/10/2026
In the Linux kernel, the following vulnerability has been resolved:
net: cpsw_new: unregister devlink on port registration failure
cpsw_probe() registers devlink before registering the CPSW ports.
If cpsw_register_ports() fails, the error path only unregisters the notifiers and then releases the lower level resources. It does not undo the successful cpsw_register_devlink() call, leaving the devlink instance and its parameters registered after probe has failed.
Add a devlink cleanup label for the path where devlink registration has already succeeded, and use it when port registration fails.
