In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix untrusted unsigned subtract
Fix the following Smatch static checker warning:
net/rxrpc/rxgk_app.c:65 rxgk_yfs_decode_ticket()
warn: untrusted unsigned subtract. 'ticket_len - 10 * 4'
by prechecking the length of what we're trying to extract in two places in
the token and decoding for a response packet.
Also use sizeof() on the struct we're extracting rather specifying the size
numerically to be consistent with the other related statements.
