CVE-2026-64344 USB: idmouse: fix use-after-free on disconnect race

In the Linux kernel, the following vulnerability has been resolved: USB: idmouse: fix use-after-free on disconnect race mutexunlock may access the mutex structure after releasing the lock and therefore cannot be used to manage lifetime of objects directly unlike spinlocks and refcounts. 12 Use a...

CVE-2026-64344

CVE-2026-64344 is a use-after-free in the Linux kernel's USB idmouse driver triggered by a disconnect race. The root cause is that mutex_unlock() is non-atomic and may still access the mutex structure after release, making it unsafe for managing object lifetime. The fix replaces direct mutex-base...

CVE-2026-64341

A use-after-free in the Linux kernel's USB iowarrior driver is triggered by a race between release() and disconnect(). Because mutex_unlock() is non-atomic, it may access a freed mutex structure after driver data is deallocated during disconnect. The fix replaces mutex-based lifetime management w...
