CVE-2025-38197

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

platform/x86: dell_rbu: Fix list usage

Pass the correct list head to list_for_each_entry*() when looping through the packet list.

Without this patch, reading the packet data via sysfs will show the data incorrectly (because it starts at the wrong packet), and clearing the packet list will result in a NULL pointer dereference.

This vulnerability is rated as Moderate impact because triggering the defect requires local access to interact with sysfs interfaces, restricting the potential harm to a denial of service through a system crash rather than arbitrary execution or information disclosure. The affected dell_rbu driver is specific to Dell hardware and is not required for standard operations. Systems running on other vendor hardware or environments where the module is not loaded are unaffected by this flaw.
