Description
In the Linux kernel, the following vulnerability has been resolved: HID: hidraw: fix data race on device refcount The hidraw_open() function increments the hidraw device reference counter. The counter has no dedicated synchronization mechanism, resulting in a potential data race when concurrently opening a device. The race is a regression introduced by commit 8590222e4b02 ("HID: hidraw: Replace hidraw device table mutex with a rwsem"). While minors_rwsem is intended to protect the hidraw_table itself, by instead acquiring the lock for writing, the reference counter is also protected. This is symmetrical to hidraw_release().

Executive Summary

This vulnerability is a data race condition in the Linux kernel's hidraw driver. Specifically, the hidraw_open() function increments a device reference counter without proper synchronization, which can lead to concurrent access issues when multiple processes open the device simultaneously. This race condition was introduced by a recent change replacing a mutex with a read-write semaphore that does not adequately protect the reference counter.

Impact Analysis

The data race on the device reference counter could lead to inconsistent or corrupted state within the hidraw device management. This might cause unexpected behavior, crashes, or resource leaks when multiple processes access the device concurrently, potentially affecting system stability or security.
