CVE-2021-47090

CVE-2021-47090 affects the Linux kernel memory manager (mm/hwpoison) where MF_COUNT_INCREASED is not cleared before retrying get_any_page, triggering a kernel BUG in release_pages() when MADV_SOFT_OFFLINE is tested. The issue leads to a kernel panic/BUG_ON scenario (VM_BUG_ON_PAGE) during page re...

CVE-2021-47088

CVE-2021-47088 concerns the Linux kernel where the DAMON debugfs interface could trigger a use-after-free by destructing monitoring targets without holding the required lock. The root cause was iterating targets in dbgfs_target_ids_read() while also destroying them in dbgfs_before_terminate() wit...
