Subject: [PATCH net] dccp: Allocate enough data in ccid_get_builtin_ccids()
Date: Wed, 26 Jul 2023 10:47:02 +0000	[thread overview]
Message-ID: <35ed2523-49ee-4e2b-b50d-38508f74f93f@moroto.mountain> (raw)

This is allocating the ARRAY_SIZE() instead of the number of bytes.  The
array size is 1 or 2 depending on the .config and it should allocate
8 or 16 bytes instead.

Fixes: ddebc973c56b ("dccp: Lockless integration of CCID congestion-control plugins")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
