Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.11.0-rc7-BTRFS-ZNS+
Description:
The issue is related to the btrfs file system in the Linux kernel. Specifically, it concerns the error propagation of split bios. The function
btrfs bbio propagate error() is intended to propagate an error of a split bio to its original btrfs bio and notify the upper layer. However, in certain cases, particularly when the end io is called quickly, the orig bbio's bio context may not be properly set, leading to a NULL pointer dereference. This can be reproduced by running btrfs/146 on zoned devices with the raid-stripe-tree feature. The error results in a kernel NULL pointer dereference.Recommendations:
To resolve the issue, update the Linux kernel to a version that includes the fix for the error propagation of split bios in the btrfs file system.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
