CVE-2026-46073

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the powerz driver. When a signal interrupt occurs during the waitforcompletioninterruptibletimeout function, the system fails to properly abort the USB Request Block URB. This oversight can lead to the kernel attempting t...
