HighMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A issue in the Linux kernel has been identified, specifically in the btrfs component. The problem arises when the submit helper fails to submit a bio, leading to potential use-after-free and NULL pointer dereference bugs due to a race condition with the endio function. This occurs because the bio is cleaned up prematurely. To address this, the repair function will continue processing the remaining pages and rely on the endio for the repair bio to handle the cleanup for the given page.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
