Description
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix an Oopsable condition in __nfs_pageio_add_request()
Ensure that nfs_pageio_error_cleanup() resets the mirror array contents,
so that the structure reflects the fact that it is now empty.
Also change the test in nfs_pageio_do_add_request() to be more robust by
checking whether or not the list is empty rather than relying on the
value of pg_count.
Affected configurations
• linux linux kernel (>= 4.0 < 5.4.124)
• linux linux kernel (>= 5.5 < 5.10.42)
• linux linux kernel (>= 5.11 < 5.12.9)
• linux linux kernel 5.13
