CVE-2023-53759

Description

In the Linux kernel, the following vulnerability has been resolved:HID: hidraw: fix data race on device refcountThe hidraw_open() function increments the hidraw device referencecounter. 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). Whileminors_rwsem is intended to protect the hidraw_table itself, by insteadacquiring the lock for writing, the reference counter is also protected.This is symmetrical to hidraw_release().
