CVE-2025-21734

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

Description A issue in the Linux kernel's fastrpc driver has been identified, where the calculation of page size for non-registered buffers does not account for the offset, potentially leading to improper and out-of-bounds page sizes being passed, resulting in memory issues. The problem arises when the driver copies the buffer and passes it to the remote subsystem.

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