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

Description A issue in the Linux kernel has been resolved, related to the handling of read-only devices in the memstick/mspro block component. The fix involves using set disk ro to propagate the read-only state to the block layer, rather than checking for it in the ->open function, which previously caused a reference leak in case of a read-only device.

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