Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> i2c: imx: Cancel hrtimer before clearing slave pointer<br /> <br /> In i2c_imx_unreg_slave(), the slave pointer is set to NULL after<br /> disabling interrupts. However, a pending interrupt might already<br /> have started the hrtimer (i2c_imx_slave_timeout) before the pointer<br /> was cleared. If the hrtimer fires after i2c_imx-&gt;slave is set to<br /> NULL, the timer callback i2c_imx_slave_finish_op() will call<br /> i2c_imx_slave_event() with a NULL slave pointer, which results in a<br /> use-after-free / NULL pointer dereference.<br /> <br /> Fix by canceling the hrtimer and waiting for it to complete after<br /> disabling interrupts, before clearing the slave pointer.
