+Subject: [PATCH] acpi: Fix out of bounds access in grub_acpi_xsdt_find_table()
+
+The calculation of the size of the table was incorrect (copy/pasta from
+grub_acpi_rsdt_find_table() I assume...). The entries are 64-bit long.
+
+This causes us to access beyond the end of the table which is causing
+crashes during boot on some systems. Typically this is causing a crash
+on VMWare when using UEFI and enabling serial autodetection, as
+
+grub_acpi_find_table (GRUB_ACPI_SPCR_SIGNATURE);
+
+Will goes past the end of the table (the SPCR table doesn't exits)
+
