  "summary": "i2c: imx: Cancel hrtimer before clearing slave pointer",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: imx: Cancel hrtimer before clearing slave pointer\n\nIn i2c_imx_unreg_slave(), the slave pointer is set to NULL after\ndisabling interrupts.  However, a pending interrupt might already\nhave started the hrtimer (i2c_imx_slave_timeout) before the pointer\nwas cleared.  If the hrtimer fires after i2c_imx->slave is set to\nNULL, the timer callback i2c_imx_slave_finish_op() will call\ni2c_imx_slave_event() with a NULL slave pointer, which results in a\nuse-after-free / NULL pointer dereference.\n\nFix by canceling the hrtimer and waiting for it to complete after\ndisabling interrupts, before clearing the slave pointer.",
