# Security digest: January 23, 2026

1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Do you run any of these? Broadcom VMware vCenter Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-02-13.
- Go: 1 critical advisory ( github.com/free5gc/nrf ). Check with govulncheck ./... .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Known exploited (CISA KEV)

- [CVE-2024-37079](https://erroneo.us/security/cve/CVE-2024-37079/index.md) Broadcom VMware vCenter Server: Broadcom VMware vCenter Server Out-of-bounds Write Vulnerability (CISA due 2026-02-13)

## Critical advisories
