SUSE CVE-2026-31529

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix leakage in constructregion Failing the first sysfsupdategroup needs to explicitly kfree the resource as it is too early for cxlregioniomemrelease to do so...

CVE-2026-31529

A flaw was found in the Linux kernel's cxl/region component. This vulnerability involves a resource leakage within the constructregion function. When sysfsupdategroup fails, the resource is not explicitly freed, leading to a memory leak. This could potentially allow a local attacker to cause a...

CVE-2026-31529

The CVE-2026-31529 issue affects the Linux kernel in the cxl/region code path. The vulnerability is a leakage (resource/memory) in __construct_region(): if sysfs_update_group() fails, the resource isn’t explicitly freed, which can lead to leakage. Several sources confirm the fix and describe the ...
