CVE-2023-53759

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