## Summary Two level errors corrupted kernel memory when a user process extended its heap with sbrk: - PGT_LAST was X86_MMU_PT_LEVELS (4), but valid levels are 0-3, so the final level entry was written with an out-of-range index. - x86_64_get_pgtable indexed the PD (level 2) with level 3, installing newly allocated page tables into the wrong PD slot. ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
