Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A hungtask bug was found in the Linux kernel's crypto component, specifically in the pcrypt module. The issue occurs when the
pinst->flags is set to PADATA RESET, causing the padata do parallel function to return an error code of -EBUSY instead of calling aead request complete(). This leads to a hung task in the test aead vec cfg function, resulting in a kernel panic. The problem is resolved by replacing the return error code -EBUSY with -EAGAIN, indicating that the parallel data is changing and the caller should retry the operation.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
