How about SELinux, like on Android?

[nromiun]

To even get the su binary on Android you have to patch the OS. So this exploit can't work on Android. Because there is no su binary to target.

Update: Just tried it on Termux and as expected even creating an AF_ALG socket requires root access.

[staticassertion]

The specific exploit payload for the POC relies on a su binary. The vuln is ambivalent and other non-su paths will exist.

[nromiun]

Of course, but it does not matter as the entire AF_ALG module is forbidden by SELinux anyway (on Android).

[staticassertion]

That's fine and a very separate reason why it would not be exploitable, also assuming that the module is not just compiled in since then loading it would be irrelevant.

[staticassertion]

I assume that wouldn't help here but I could easily be wrong. (Assuming if you're asking if SELinux would block this exploit).

selinux on enforcement mode did not mitigate the exploit when I tested today on fedora coreos :(
