Description OSIDB Bzimport 2025-03-27 17:02:20 UTC 
In the Linux kernel, the following vulnerability has been resolved:

EDAC/highbank: Fix memory leak in highbank_mc_probe()

When devres_open_group() fails, it returns -ENOMEM without freeing memory
allocated by edac_mc_alloc().

Call edac_mc_free() on the error handling path to avoid a memory leak.
