In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file. https://github.com/torvalds/linux/blob/1c33bb0507508af24fd754dd7123bd8e997fab2f/arch/x86/include/asm/elf.h#L281-L294 https://github.com/x0reaxeax/exec-prot-bypass
