CVE-2023-53130: block: fix wrong mode for blkdev_put() from disk_scan_partitions()
First published: Fri May 02 2025(Updated: )
In the Linux kernel, the following vulnerability has been resolved: block: fix wrong mode for blkdev_put() from disk_scan_partitions() If disk_scan_partitions() is called with 'FMODE_EXCL', blkdev_get_by_dev() will be called without 'FMODE_EXCL', however, follow blkdev_put() is still called with 'FMODE_EXCL', which will cause 'bd_holders' counter to leak. Fix the problem by using the right mode for blkdev_put().
