CVE-2024-26751

Kernel oops via unterminated GPIO lookup table

Published Apr 3, 2024 · Updated May 11, 2026

Denial of service in affected Linux kernel builds allows local users to trigger a kernel oops through an EP93xx GPIO lookup. The EP93xx platform table in arch/arm/mach-ep93xx/core.c lacks a terminating empty entry, so gpio_find continues past the table for an unknown con_id instead of stopping. The path requires low-privileged local access to an EP93xx ARM system and a nonexistent connection identifier; the resulting oops interrupts kernel operation.
