Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
In the dm driver, the failure to implement its own timeout handler while relying on slave devices leads to an issue where requests are leaked and never completed if an
io-timeout-fail error is injected. This occurs because the driver does not correctly handle the blk should fake timeout() check, which can cause tasks to hang indefinitely.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
