PUB-A-511808317: Integer Overflow

Q: What level of access does an attacker need to exploit this issue?

Exploitation requires System execution privileges. No user interaction is required.

Q: What is the potential impact if exploitation succeeds?

The issue could allow local escalation of privilege through overlapping memory mappings created by an integer-overflow wraparound.

Published Nov 1, 2026

Updated

In multiple functions of vaddrlist.c, there is a possible way to create overlapping memory mappings via an aligned size wraparound due to an integer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
