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.

Affected configurations

• linux linux kernel (>= 2.6.37 < 4.4.271) • linux linux kernel (>= 4.5 < 4.9.271) • linux linux kernel (>= 4.10 < 4.14.235) • linux linux kernel (>= 4.15 < 4.19.193) • linux linux kernel (>= 4.20 < 5.4.124) • linux linux kernel (>= 5.5 < 5.10.42) • linux linux kernel (>= 5.11 < 5.12.9) • linux linux kernel 5.13
