Detailsinfo

A vulnerability was found in Linux Kernel up to 6.14.6/6.15-rc5. It has been rated as critical. This issue affects the function opt3001_irq. The manipulation with an unknown input leads to a deadlock vulnerability. Using CWE to declare the problem leads to CWE-833. The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock. Impacted is availability. The summary by CVE is:

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

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2025-37968 since 04/16/2025. The exploitation is known to be difficult. Technical details are known, but no exploit is available.
