CVE ID : CVE-2025-37880
Published : May 9, 2025, 7:16 a.m. | 4 hours, 51 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved:
um: work around sched_yield not yielding in time-travel mode
sched_yield 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 (CONFIG_UML_MAX_USERSPACE_ITERATIONS).
Work around it by accounting time to the process whenever it executes a
sched_yield syscall.
Severity: 0.0 | NA
