    Оригинално описание

    In the Linux kernel, the following vulnerability has been resolved: platform/x86: intel-hid: Protect ACPI notify handler against recursion Since commit e2ffcda16290 ("ACPI: OSL: Allow Notify () handlers to run on all CPUs") ACPI notify handlers like the intel-hid notify_handler() may run on multiple CPU cores racing with themselves. On convertibles and detachables (matched by DMI chassis-type 31 and 32 in dmi_auto_add_switch[]) the SW_TABLET_MODE input device is registered lazily from notify_handler() on the first tablet-mode event, via intel_hid_switches_setup(). When two such events race on different CPUs both can pass the !priv->switches check and register the priv->switches input device twice, resulting in a duplicate sysfs entry and a subsequent NULL pointer dereference. This is the same class of bug fixed by commit e075c3b13a0a ("platform/x86: intel-vbtn: Protect ACPI notify handler against recursion") for the sibling intel-vbtn driver. Protect intel-hid notify_handler() from racing with itself with a mutex to fix this.
