they were used in 2020, 2021, and 2022 pwn2own exploits. Sorry I don't remember the exact numbers and will have to dig.

pwn2own 2023 4/5 hacks used them

I will need to dig to find the CVEs associated with them.

pwn2own 2024 I can not discuss atm

but its not just pwn2own, the actual list of kernel CVEs that unprivileged user namespaces make exploitable is much larger.
