Subject: [PATCH v1 1/4] net/ice/base: fix integer overflow on NVM init
Date: Tue, 30 Sep 2025 12:21:14 +0100	[thread overview]
Message-ID: <664899c1791adcfc6e53fdac5ff9eb65e2fbec7a.1759231103.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1759231103.git.anatoly.burakov@intel.com>

From: Chinh Cao <chinh.t.cao@intel.com>

The shadow RAM size is defined as 16-bit unsigned, which may result in
overflows under certain scenarios. Fix the value to be 32-bit.

Fixes: a240ff50505b ("net/ice/base: add basic structures")
Cc: stable@dpdk.org
