This update for the Linux Kernel 3.12.74-60_64_115 fixes several issues.

The following security issues were fixed :

CVE-2020-12653: Fixed a buffer overflow in mwifiex_cmd_append_vsie_tlv() which could have allowed local users to gain privileges or cause a denial of service (bsc#1171254).

CVE-2020-12654: Fixed a heap-based buffer overflow in mwifiex_ret_wmm_get_status() which could have been triggered by a remote AP to trigger (bsc#1171252).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
