Intel SMM Buffer OOB Read/Write via Improper Input Validation
CVE-2024-36310 Published on February 10, 2026
Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity.
Weakness Type
What is a buffer underrun Vulnerability?
The software writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer. This typically occurs when a pointer or its index is decremented to a position before the buffer, when pointer arithmetic results in a position before the beginning of the valid memory location, or when a negative index is used.
CVE-2024-36310 has been classified to as a buffer underrun vulnerability or weakness.
