Subject: [PATCH AUTOSEL 6.3 14/59] bnxt: avoid overflow in bnxt_get_nvram_directory()
Date: Thu,  4 May 2023 15:40:57 -0400	[thread overview]
Message-ID: <20230504194142.3805425-14-sashal@kernel.org> (raw)
In-Reply-To: <20230504194142.3805425-1-sashal@kernel.org>

From: Maxim Korotkov <korotkov.maxim.s@gmail.com>

[ Upstream commit 7c6dddc239abe660598c49ec95ea0ed6399a4b2a ]

The value of an arithmetic expression is subject
of possible overflow due to a failure to cast operands to a larger data
type before performing arithmetic. Used macro for multiplication instead
operator for avoiding overflow.

Center (linuxtesting.org) with SVACE.
