CVE-2022-49757 Details
Description
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. [ bp: Massage commit message. ]
A memory leak vulnerability has been identified in the Linux kernel's EDAC/highbank component. The issue arises in the highbank_mc_probe() function, where the error handling path fails to release memory allocated by edac_mc_alloc() when devres_open_group() returns an error. This oversight leads to a memory leak.
