# CVE-2026-74461

> 8.4 HIGH

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

i2c: imx: Cancel hrtimer before clearing slave pointer

In i2c_imx_unreg_slave(), the slave pointer is set to NULL after
disabling interrupts.  However, a pending interrupt might already
have started the hrtimer (i2c_imx_slave_timeout) before the pointer
was cleared.  If the hrtimer fires after i2c_imx->slave is set to
NULL, the timer callback i2c_imx_slave_finish_op() will call
i2c_imx_slave_event() with a NULL slave pointer, which results in a
use-after-free / NULL pointer dereference.

Fix by canceling the hrtimer and waiting for it to complete after
disabling interrupts, before clearing the slave pointer.
