Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.0-rc1-00134-gb9ed6de8d4ff #7
Description
The Linux kernel contains a flaw within the rcuscale functionality. Specifically, the
rcuscale.holdoff module parameter can be manipulated to delay the start of the rcu scale writer() kthread. If the timeout specified by rcuscale.holdoff exceeds the hung task timeout secs setting, the system may enter a hung task state. The issue is related to the use of schedule timeout uninterruptible() within the rcu scale writer() function. This has been addressed by replacing schedule timeout uninterruptible() with schedule timeout idle().Recommendations
Update to Linux kernel version 6.4.0-rc1-00134-gb9ed6de8d4ff #7 or a later version to resolve this issue.
