Who should care
System administrators, security teams, and users of affected systems should be aware of this vulnerability and take necessary actions to mitigate it. Affected operators and platforms should review the vulnerability and implement compensating controls if necessary.
Technical summary
An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure. The vulnerability affects GPU drivers and has a high impact on system security.
Defensive priority
High
Recommended defensive actions
