CVE-2022-50006

CVE-2022-50006 affects the Linux kernel in NFSv4.2 handling of __nfs42_ssc_open. The issue arises when a destination server processes a COPY and should not accept a passed filehandle if it’s not a regular filehandle; additionally, if alloc_file_pseudo() fails, the kernel must drop the reference t...
