2024-01-26StandaloneMmPkg/Hob: Integer Overflow in CreateHob()Gua Guo1-0/+35
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4166 Fix integer overflow in various CreateHob instances. Fixes: CVE-2022-36765 The CreateHob() function aligns the requested size to 8 performing the following operation: ``` HobLength = (UINT16)((HobLength + 0x7) & (~0x7)); ``` No checks are performed to ensure this value doesn't overflow, and could lead to CreateHob() returning a smaller HOB than requested, which could lead to OOB HOB accesses.

2018-07-20StandaloneMmPkg/HobLib: Add HOB Library for management mode.Supreeth Venkatesh3-0/+719
The Standalone MM environment is initialized during the SEC phase on ARM Standard Platforms. The MM Core driver implements an entry point module which is architecture specific and runs prior to the generic core driver code. The former creates a Hob list that the latter consumes. This happens in the same phase. This patch implements a Hob library that can be used by the entry point module to produce a Hob list and by the core driver code to consume it.
