What it is

In the Linux kernel, the following vulnerability has been resolved:

cifs: Fix oops due to uninitialised variable

Fix smb3_init_transform_rq() to initialise buffer to NULL before calling

netfs_alloc_folioq_buffer() as netfs assumes it can append to the buffer it

is given. Setting it to NULL means it should start a fresh buffer, but the

value is currently undefined.
