CVE-2025-38381

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

Input: cs40l50-vibra - fix potential NULL dereference in cs40l50_upload_owt()

The cs40l50_upload_owt() function allocates memory via kmalloc() without checking for allocation failure, which could lead to a NULL pointer dereference.

Return -ENOMEM in case allocation fails.
