Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.58
Description:
The issue is related to the io uring feature in the Linux kernel, where an overflow can cause a significant delay during flushing. Normally, this list is empty, but an application can overflow it, and in extreme cases, like those generated by syzbot, flushing can take a long time. The fix involves checking if rescheduling is needed during overflow flush and dropping locks to do so if necessary.
Recommendations:
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider restricting the use of io uring to minimize the risk of exploitation.
