Summary
In the Linux kernel, the following vulnerability has been resolved:
isofs: release zisofs block pointer buffer head
zisofs_fill_pages() reads the compressed block pointer table. The error paths release the current buffer_head, the loop also releases the old buffer_head when it advances. However, the success path leaves the last buffer_head referenced. Release it before returning success.
