CVE-2026-46005 Details
Description
In the Linux kernel, the following vulnerability has been resolved: xfs: fix a resource leak in xfs_alloc_buftarg() In the error path, call fs_put_dax() to drop the DAX device reference.
A resource leak vulnerability has been identified in the Linux kernel's XFS file system, specifically within the buffer allocation function. This vulnerability arises from improper management of Direct Access (DAX) device references, which can lead to resource leaks. The issue is present in the error handling path of the 'xfs_alloc_buftarg()' function, where the DAX device reference is not properly released. As a result, the vulnerability can cause a gradual depletion of system resources, potentially leading to performance degradation or exhaustion of available resources.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability. The patch can be downloaded from the Linux kernel Git repository.
