CVE-2026-97451
ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op)
Description
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op) Add overflow check for Index + Length to prevent integer overflow when calculating the truncation length. This prevents negative size parameter being passed to memcpy().
