      <Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">In the Linux kernel, the following vulnerability has been resolved:

ipv6: fix another slab-out-of-bounds in fib6_nh_flush_exceptions

While running the self-tests on a KASAN enabled kernel, I observed a
slab-out-of-bounds splat very similar to the one reported in
commit 821bbf79fe46 ("ipv6: Fix KASAN: slab-out-of-bounds Read in
 fib6_nh_flush_exceptions").

We additionally need to take care of fib6_metrics initialization
failure when the caller provides an nh.

The fix is similar, explicitly free the route instead of calling
fib6_info_release on a half-initialized object.</Note>

sch_cake: do not call cake_destroy() from cake_init()

qdiscs are not supposed to call their own destroy() method
from init(), because core stack already does that.
