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.","state":0,"publishedAt":"2026-08-15T12:27:01.924+00:00","modifiedAt":"2026-10-16T19:05:47.029+00:00","affected":[{"ecosystem":"Vendor
