CVE-2024-49911

Local system crash via unchecked gamma callback

Published Oct 21, 2024 · Updated May 11, 2026

A NULL pointer dereference in Linux allows local users to crash systems through AMD display output-transfer configuration. dcn20_set_output_transfer_func checks set_output_gamma earlier in the path but later calls the function pointer without another NULL guard. Exploitation requires low-privileged local access and an affected AMD display path; confidentiality and integrity remain unaffected.
