CVE-2026-43055

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In the target core file component, the aio cmd structure does not properly initialize the iocb for the ki write stream. During the execution of a write command via the fd execute rw aio() function, a bogus ki write stream value may be generated. This can lead to unintended write failure statuses when the system checks if iocb->ki write stream exceeds max write streams in the block device.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
