CVE-2023-54010

Kernel crash via unchecked ACPICA allocation

Published Dec 24, 2025 · Updated Dec 24, 2025

Null-pointer dereference in Linux kernel ACPICA allows local users to crash the kernel through the ACPI debugger's object display command. The acpi_db_display_objects function allocates object_info with ACPI_ALLOCATE_ZEROED but previously used the pointer without checking for allocation failure. Exploitation requires that allocation to fail while the function runs; the published impact is limited to availability loss.
