**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the block layer in the Linux kernel, where there is no check to ensure that the partition length is aligned with the logical block size before adding or resizing a partition. If the logical block size of the disk is larger than 512 bytes, the partition size may not be a multiple of the logical block size, resulting in an IO error when the last sector is read and `bio truncate()` adjusts the bio size. Additionally, if integrity data is supported, this can lead to a null pointer dereference when calling `bio integrity free()`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
