CVE-2026-64512

In CVE-2026-64512, a Linux kernel issue in the ACPI CPPC module stems from field misuse of reg->access_width depending on reg->space_id. When using ACPI_ADR_SPACE_PLATFORM_COMM, access_width indicates the PCC region and can trigger UBSAN shift-out-of-bounds, as illustrated by UBSAN: shift-o...

CVE-2026-64510

CVE-2026-64510 affects the Linux kernel and concerns the ACPI NFIT core. The vulnerability arises when acpi_nfit_init() fails after adding an acpi_desc to the acpi_descs list or when certain probe/update paths do not register a proper shutdown/remove path. This can lead to a use-after-free in nfi...

CVE-2026-64511

CVE-2026-64511 concerns the Linux kernel where an ACPI NFIT NULL-pointer dereference could occur if NFIT_NOTIFY_UC_MEMORY_ERROR arrives before the NFIT table is allocated. The fix guards acpi_nfit_uc_error_notify() against a NULL acpi_desc, preventing dereferencing when the NFIT table is absent a...
