CVE-2026-31552

A flaw was found in the Linux kernel's wlcore component. When the system attempts to allocate memory for a network packet and there is insufficient space, an incorrect error code is returned. This error handling issue causes the system to repeatedly attempt to process the same packet in an endless loop, leading to a CPU soft lockup. This can result in a Denial of Service (DoS) for the affected system.

This vulnerability is rated as Moderate impact because it results only in a denial of service (CPU soft lockup) without exposing sensitive information or allowing privilege escalation, and it requires the presence of specific hardware. The issue affects the Texas Instruments wlcore wireless driver, which is not used in standard enterprise server deployments. Consequently, systems lacking this wireless chipset hardware are not exposed to this flaw during typical operations.
