Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue concerns a memory handling bug in the Linux kernel's buffered reads, specifically in the
netfs read to pagecache() function. When this function encounters an error from either ->prepare read() or netfs prepare read iterator(), it needs to decrement ->nr outstanding, cancel the subrequest, and break out of the issuing loop. However, this handling was only done for two of the cases, leaving two more unhandled. The fix involves moving the handling to a common place and jumping to it from all four places, rather than inserting a wrapper around netfs prepare read iterator().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
