Local system crash via unchecked bus callback
Published Jun 18, 2025 · Updated May 11, 2026
NULL pointer dereference in Linux kernel 6.13 through 6.14.7 and 6.15-rc1 through 6.15-rc5 allows local users to crash the system. The ad7616_sw_mode_setup() and ad7606b_sw_mode_setup() paths call the bus operations sw_mode_config pointer without first checking whether the selected bus implements that callback. Exploitation requires local low-privileged access and an affected AD7616 or AD7606B ADC configured for software mode on a bus without the callback; the bounded consequence is a kernel crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
