CRITICAL · CVSS 3.1 · EPSS 10.8% (pctl 96)
Patch early
EPSS 10.8% — above the 10% action threshold.
Description
The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.
