Pwn2Own Toronto 2023 final-day live update summarizing contest outcomes: Foundry Zero failed to complete an exploit for a Lexmark device, while ANHTUD and Interrupt Labs successfully executed multi-bug chains (including stack buffer overflows, a use-after-free, and an integer underflow) against TP-Link, Canon, and Sonos devices; several successful chains involved previously known bugs resulting in “bug collision” notes and adjusted prizes/points.
