Out-of-bounds reads via truncated AML resource descriptors
Published Sep 24, 2026 · Updated Sep 24, 2026
Out-of-bounds reads in Linux before 6.12.111 and 6.18.53 allow attackers to cause unspecified impact via malformed AML resource descriptors. The acpi_ut_walk_aml_resources() loop reads descriptor header and SerialBus type fields and accepts a declared length beyond the remaining AML buffer. Linux has not published how attackers can supply the AML buffer or whether the over-read causes disclosure, a crash, or another consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
