CVE-2024-50117
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/amd: Guard against bad data for ATIF ACPI method
If a BIOS provides bad data in response to an ATIF method call this causes a NULL pointer dereference in the caller.
It has been encountered on at least one system, so guard for it.
(cherry picked from commit c9b7c809b89f24e9372a4e7f02d64c950b07fdee)
