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...
