CVE-2024-50194

Process corruption via byte-swapped uprobe instruction handling

Published Nov 8, 2024 · Updated May 11, 2026

Improper instruction handling in affected Linux kernels allows local users to corrupt probed process execution on big-endian arm64 systems. The arm64 uprobes analyzer reads little-endian bytes as native u32 values, so byte-swapped opcodes can be rejected, stepped unsafely, or simulated incorrectly. Exploitation requires local low-privileged access and an active uprobe on a vulnerable big-endian arm64 kernel; the demonstrated consequence is incorrect process output.
