CVE-2026-46221
Last modified
CVE-2026-46221 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: EDAC/versalnet: Fix device name memory leak The device name allocated via kzalloc() in init_one_mc() is assigned to dev->init_name but never freed on the normal removal path. device_register() copies init_name and then sets dev->init_name to NULL, so the name pointer becomes unreachable from the device. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
Description
In the Linux kernel, the following vulnerability has been resolved: EDAC/versalnet: Fix device name memory leak The device name allocated via kzalloc() in init_one_mc() is assigned to dev->init_name but never freed on the normal removal path. device_register() copies init_name and then sets dev->init_name to NULL, so the name pointer becomes unreachable from the device. Thus leaking memory. Use a stack-local char array instead of using kzalloc() for name.
