CVE-2026-31529
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.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (Other); DoS: Resource Consumption (Memory); DoS: Resource Consumption (CPU)
An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. Frequently-affected resources include memory, CPU, disk space, power or battery, etc.
