"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: intel-hid: Protect ACPI notify handler against recursion\n\nSince commit e2ffcda16290 (\"ACPI: OSL: Allow Notify () handlers to run on\nall CPUs\") ACPI notify handlers like the intel-hid notify_handler() may\nrun on multiple CPU cores racing with themselves.\n\nOn convertibles and detachables (matched by DMI chassis-type 31 and 32 in\ndmi_auto_add_switch[]) the SW_TABLET_MODE input device is registered\nlazily from notify_handler() on the first tablet-mode event, via\nintel_hid_switches_setup(). When two such events race on different CPUs\nboth can pass the !priv->switches check and register the priv->switches\ninput device twice, resulting in a duplicate sysfs entry and a subsequent\nNULL pointer dereference.\n\nThis is the same class of bug fixed by commit e075c3b13a0a (\"platform/x86:\nintel-vbtn: Protect ACPI notify handler against recursion\") for the\nsibling intel-vbtn driver.\n\nProtect intel-hid notify_handler() from racing with itself with a mutex\nto fix this."
