Detailed explanation of slab allocator’s internals with illustrations. Linux kernel version isn’t too old (5.3.13), so the article is still relevant.

Short article about some structures that can be used for linux kernel exploitation. It is worth transferring this notes to the database, just in case, because researcher did a big work evaluating the usefulness of each interface. Language - Japanese.

Recently, I found a great article by Brandon Azad (short summary) about all Iphone’s hardware and software mitigations ( IOS < 13, so PAC not covered ). I recommend to study the material, at least for improving general purview :)
