NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf-debuginfo package and not the python-perf-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

NFS: fix an incorrect limit in filelayout_decode_layout()

The "sizeof(struct nfs_fh)" is two bytes too large and could lead to memory corruption. It should be NFS_MAXFHSIZE because that's the size of the ->data[] buffer.

I reversed the size of the arguments to put the variable on the left.
