CVE-2024-26978Public exploit

Kernel crash via unchecked I2C device match data

Published May 1, 2024 · Updated May 23, 2026

NULL pointer dereference in affected Linux kernels allows local users to crash the kernel via max14830 I2C instantiation. The max310x_i2c_probe function treats missing device match data as a devtype pointer and dereferences it while validating the client address. Reaching the flaw requires local permission to create an I2C device through sysfs, and successful triggering interrupts availability through a kernel oops.
