[seL4] LionsOS musllibc old version? Vulnerable?

Hi, reading the dependencies of LionsOS I realized it is using an old version of muslibc : https://github.com/au-ts/musllibc/blob/81842bc43d0b49bbcca03ff5f506c6df8e2bd... if this version has not been patched may be vulnerable to a remotely exploitable buffer overflow in the dns resolution: https://git.musl-libc.org/cgit/musl/commit/?id=45ca5d3fcb6f874bf5ba55d0e9651... Can someone confirm or reject? Thanks.
