  "details": "In the Linux kernel, the following vulnerability has been resolved:  hwmon: (lm90) Add lock protection to lm90_alert  Sashiko reports:  lm90_alert() executes in the smbus alert context and calls lm90_update_confreg() to disable the hardware alert line, without acquiring hwmon_lock.  Concurrently, sysfs write operations (such as lm90_write_convrate) hold the hwmon_lock, temporarily modify data-\u003econfig, and then restore it.  If an alert interrupt occurs concurrently with a sysfs write, the sysfs path will overwrite the alert handler's modifications to data-\u003econfig and the hardware register.  This unintentionally re-enables the hardware alert line while the alarm is still active, causing an interrupt storm.  Add the missing lock to lm90_alert() to solve the problem.",
