CVE-2021-47168
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.
Does this matter?
Lower severity and a low EPSS score (0.76%). Track it; it rarely justifies an emergency change on its own.
Description
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.
