CVE-2022-50675 arm64: mte: Avoid setting PG_mte_tagged if no tags cleared or restored

In the Linux kernel, the following vulnerability has been resolved: arm64: mte: Avoid setting PGmtetagged if no tags cleared or restored Prior to commit 69e3b846d8a7 "arm64: mte: Sync tags for pages where PTE is untagged", mtesynctags was only called for ptetagged entries those mapped with PROTMT...

CVE-2022-50675

The CVE concerns Linux kernel arm64 MTE tagging. Before commit 69e3b846d8a7, mte_sync_tags() would run for pages that looked untagged but could set PG_mte_tagged via test_and_set_bit on such pages, potentially tagging swap/migration pages and propagating tags during copy/migration. The issue was ...

NanoTag: Systems Support for Efficient Byte-Granular Overflow Detection on ARM MTE

Memory safety bugs, such as buffer overflows and use-after-frees, are the leading causes of software safety issues in production. Software-based approaches, e.g., Address Sanitizer ASAN, can detect such bugs with high precision, but with prohibitively high overhead. ARM's Memory Tagging Extension...
