Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: light: opt3001: fix deadlock due to concurrent flag access<br /> <br /> The threaded IRQ function in this driver is reading the flag twice: once to<br /> lock a mutex and once to unlock it. Even though the code setting the flag<br /> is designed to prevent it, there are subtle cases where the flag could be<br /> true at the mutex_lock stage and false at the mutex_unlock stage. This<br /> results in the mutex not being unlocked, resulting in a deadlock.<br /> <br /> Fix it by making the opt3001_irq() code generally more robust, reading the<br /> flag into a variable and using the variable value at both stages.
