Name of the Vulnerable Software and Affected Versions libkcapi (affected versions not specified)
Description Memory corruption occurs in the one-shot AIO (Asynchronous I/O) path of libkcapi. The issue arises when the path returns an error before all submitted IOCBs (I/O Control Blocks) are drained, which allows subsequent kernel writes to occur within output buffers owned by the caller.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
