CVE-2023-54297

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: zoned: fix memory leak after finding block group with super blocks<br /> <br /> At exclude_super_stripes(), if we happen to find a block group that has<br /> super blocks mapped to it and we are on a zoned filesystem, we error out<br /> as this is not supposed to happen, indicating either a bug or maybe some<br /> memory corruption for example. However we are exiting the function without<br /> freeing the memory allocated for the logical address of the super blocks.<br /> Fix this by freeing the logical address.
