(CVE-2019-13272)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
* [kernel-alt]: BUG: unable to handle kernel NULL pointer IP:
crypto_remove_spawns+0x118/0x2e0 (BZ#1536967)
* [HPE Apache] update ssif max_xmit_msg_size limit for multi-part messages
