Description

A flaw was found in the Linux kernel's cxl/region component. This vulnerability involves a resource leakage within the __construct_region() function. When sysfs_update_group() fails, the resource is not explicitly freed, leading to a memory leak. This could potentially allow a local attacker to cause a Denial of Service (DoS) by exhausting system resources.

Mitigation

No mitigation is specified in collected source.
