Subject: [PATCH] nfc: s3fwrn5: Prefer strscpy() over strcpy()
Date: Wed, 30 Oct 2024 03:46:34 +0530 [thread overview]
Message-ID: <20241029221641.15726-1-abdul.rahim@myyahoo.com> (raw)
In-Reply-To: 20241029221641.15726-1-abdul.rahim.ref@myyahoo.com
strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors [1]
this fixes checkpatch warning:
WARNING: Prefer strscpy over strcpy
