Summary
In the Linux kernel, the following vulnerability has been resolved: bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem The vmemmap pages is marked by kmemleak when allocated from memblock. Remove it from kmemleak when freeing the page. Otherwise, when we reuse the page, kmemleak may report such an error and then stop working. kmemleak: Cannot insert 0xffff98fb6eab3d40 into the object search tree (overlaps existing) kmemleak: Kernel memory leak detector disabled kmemleak: Object 0xffff98fb6be00000 (size 335544320): kmemleak: comm "swapper", pid 0, jiffies 4294892296 kmemleak: min_count = 0 kmemleak: count = 0 kmemleak: flags = 0x1 kmemleak: checksum = 0 kmemleak: backtrace:
