In the Linux kernel, the following vulnerability has been resolved:
um: work around sched_yield not yielding in time-travel mode
schedyield by a userspace may not actually cause scheduling in time-travel mode as no time has passed. In the case seen it appears to be a badly implemented userspace spinlock in ASAN. Unfortunately, with time-travel it causes an extreme slowdown or even deadlock depending on the kernel configuration (CONFIGUMLMAXUSERSPACE_ITERATIONS).
Work around it by accounting time to the process whenever it executes a sched_yield syscall.
