CVE-2025-38197 Details
Description
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.
A vulnerability in the Linux kernel's handling of the Dell RBU (Remote BIOS Update) feature can lead to a NULL pointer dereference. This issue arises from incorrect list management when processing packet data via sysfs. The vulnerability affects several versions of the Linux kernel.
