GHSA-H772-36JH-J5R8

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-17 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

watchdog: sp5100_tco: Fix a memory leak of EFCH MMIO resource

Unlike release_mem_region(), a call to release_resource() does not free the resource, so it has to be freed explicitly to avoid a memory leak.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
