What to do
AI-suggested
A fix has been applied in the Linux kernel source code to ensure a non-null pointer is passed to dcn20_validate_apply_pipe_split_flags, resolving the null dereference. Users should update to the fixed kernel version once available from their distribution or vendor. No additional mitigation is indicated.
Description
A null pointer dereference vulnerability in the Linux kernel's AMD display driver (dcn20_validate_apply_pipe_split_flags) was fixed by ensuring a non-null pointer is passed. This resolves two forward null dereference issues identified by static analysis.
