Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 5.15.196/6.1.158/6.6.118/6.12.60/6.17.10. Affected by this vulnerability is the function bmc150_accel_set_interrupt of the file bmc150-accel-core.c of the component driver. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: iio: accel: bmc150: Fix irq assumption regression The code in bmc150-accel-core.c unconditionally calls bmc150_accel_set_interrupt() in the iio_buffer_setup_ops, such as on the runtime PM resume path giving a kernel splat like this if the device has no interrupts: Unable to handle kernel NULL pointer dereference at virtual address 00000001 when read PC is at bmc150_accel_set_interrupt+0x98/0x194 LR is at __pm_runtime_resume+0x5c/0x64 (...)

Store the IRQ number in the state struct, as this is a common pattern in other drivers, then use this to determine if we have IRQ support or not.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2025-68330 since 12/16/2025. The exploitation appears to be difficult. Technical details are known, but no exploit is available.
