Greg Kroah-Hartman has released the 6.6.133 stable kernel. This reverts
a backporting mistake that removed file descriptor checks which
led to kernel panics if the fgetxattr, flistxattr,
fremovexattr, or fsetxattr functions were called
from user space with a file descriptor that did not reference an open
file.
