CVE-2021-47168

תיאור (מקור, אנגלית)

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.
