- Summary
- CVE-2024-39292 affecting package kernel for versions less than 5.15.162.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
um: Add winch to winch_handlers before registering winch IRQ
Registering a winch IRQ is racy, an interrupt may occur before the winch is added to the winch_handlers list.
If that happens, registerwinchirq() adds to that list a winch that is scheduled to be (or has already been) freed, causing a panic later in winch_cleanup().
Avoid the race by adding the winch to the winchhandlers list before registering the IRQ, and rolling back if umrequest_irq() fails.
