Description SMASH SMASH 2024-02-16 08:40:20 UTC

https://nodejs.org/en/blog/vulnerability/february-2024-security-releases/

setuid() does not drop all privileges due to io_uring (CVE-2024-22017) - (High)

setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid().

This allows the process to perform privileged operations despite presumably having dropped such privileges through a call to setuid().

Impacts:

    This vulnerability affects all users in active release lines: 20.x, and 21.x.

Thank you, to valette for reporting this vulnerability and thank you Tobias Nießen for fixing it.
