CVE-2023-54285

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

Description An issue exists in the Linux kernel related to a potential overflow condition within the iomap write delalloc scan function. The folio next index() function returns an unsigned long value, and when left-shifted by PAGE SHIFT on 32-bit systems, this could lead to an overflow. The corrected approach utilizes folio pos(folio) + folio size(folio) to accurately calculate the index.

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