Probably not.&lt;p&gt;This - as far as I can tell - affects userspace processes only. Jailbreaks require a kernel exploit. (The Apple Security release notes says that this bug may allow “arbitrary code with kernel privileges”, but I can’t see how.)&lt;p&gt;You might still do something cool on iOS with this, but I’m not sure what you’d overwrite: codesigning should protect all executables and libraries. (I have not tested this: let me know if you find anything!)&amp;quot;&lt;p&gt;Looks like system integrity protection? or some other mechanism preventing this?</text><parent_chain></parent_chain></comment><story><title>Get root on macOS 13.0.1 the macOS Dirty Cow bug</title><url>https://worthdoingbadly.com/macdirtycow/</url></story>
