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.

Notes

Author Note
sbeattie this is in place so that ancient binaries will continue to work; if an attacker can link a modern binary to allow this, they could just create and execute a binary. need to validate that we don’t ever ship binaries without GNU_PT_STACK
