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

How can CyberStrike help with CVE-2023-54297?
CyberStrike is an open-source, AI-augmented pentesting engine.
