I don't know why you're still using OpenSSL but if you're able to switch I note that BoringSSL was not affected by any of the January 2026 OpenSSL advisories, and was also not affected by any of the advisories from 2025, and was affected by only one of the 2024 advisories. I also note that I don't see any hasty commit activity to s2n-tls that looks like a response to these advisories.
Better software is out there.
I wanted to mention WolfSSL.
I like to recommend that project because it has a very transparent vulnerabilities approach, and is in my opinion written a lot more sane than OpenSSL which is somewhat not using standard C features because it always implements everything from scratch like a kernel does.
But yeah, anyways, WolfSSL comes from the embedded area in case that's your thing.
