Description OSIDB Bzimport 2026-01-05 10:02:25 UTC
In the Linux kernel, the following vulnerability has been resolved:

staging: most: remove broken i2c driver

The MOST I2C driver has been completely broken for five years without
anyone noticing so remove the driver from staging.

Specifically, commit 723de0f9171e ("staging: most: remove device from
interface structure") started requiring drivers to set the interface
device pointer before registration, but the I2C driver was never updated
which results in a NULL pointer dereference if anyone ever tries to
probe it.
