NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-debug package and not the kernel-rt-64k-debug package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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.
