Positive Technologies (AI Summary)

CVSS v3.1

7.5

High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

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

Description: The issue is related to the bio truncate() function in the Linux kernel, which clears the buffer outside of the last block of a block device. However, the function is using the wrong offset of a page, potentially returning uninitialized data. This can occur when both a truncated or corrupted file system and userspace (via a block device) are trying to read the last block of the device.

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