BugLink: https://bugs.launchpad.net/bugs/2040284 [ Upstream commit 9e47a758b70167c9301d2b44d2569f86c7796f2d ] During NVMeTCP Authentication a controller can trigger a kernel oops by specifying the 8192 bit Diffie Hellman group and passing a correctly sized, but zeroed Diffie Hellamn value. mpi_cmp_ui() was detecting this if the second parameter was 0, but 1 is passed from dh_is_pubkey_valid(). This causes the null pointer u->d to be dereferenced towards the end of mpi_cmp_ui() Signed-off-by: Mark O'Donovan <shiftee@posteo.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Roxana Nicolescu <roxana.nicolescu@canonical.com> Signed-off-by: Stefan Bader <stefan.bader@canonical.com> |
