GHSA-qc66-pxrq-vq8r PUBLISHED CVSS 8.699999809265137 HIGH

Record from GitHub Advisory Database · Published May 1, 2022

Linux kernel 2.6.x, when using both NFS and EXT3, allows remote attackers to cause a denial of service (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), which triggers an error and causes an exported directory to be remounted read-only.
