CVE-2026-43356

Kernel crash via unchecked ADIS ops pointer

Published May 8, 2026 · Updated May 8, 2026

NULL pointer dereference in the IIO ADIS helper in Linux Kernel 6.15 allows attackers to crash the kernel during driver probing. The adis_init() function reads adis->ops function pointers before checking whether adis->ops is NULL, even though device allocation zero-initializes that field. Exposure requires probing an affected ADIS driver that relies on default operations; no remote or user-controlled trigger is documented.
