kmalloc redzone

The kmalloc redzone tag covers kernel memory debugging related to the SLUB allocator's redzone feature, which detects buffer overflows by placing markers after allocated memory. A notable topic is CVE-2024-49885, a bug where a flaw in handling kmalloc redzones during SLUB debugging with init_on_free can cause kernel panics and system instability. This affects Linux kernel stability and is relevant for system administrators and cloud operators managing patching and mitigation. Discussions include the bug's mechanism, affected kernel versions, upstream fixes, and detection steps. The tag focuses on Linux kernel memory management, debugging, and security vulnerabilities rather than Windows or general IT topics.
