Subject: [PATCH] elf/tlsdeschtab.h: Add the Malloc return value check in _dl_make_tlsdesc_dynamic()
Date: Fri, 4 Nov 2022 17:30:00 +0800 [thread overview]
Message-ID: <20221104093000.25169-1-nixiaoming@huawei.com> (raw)
Check the return value of malloc based on the function header comment of
_dl_make_tlsdesc_dynamic(). If the return value fails, NULL is returned.
