RLSA-2026:98671: Important: nginx:1.24 security update

Q: Which deployments are affected by this advisory?

The advisory applies to Rocky Linux systems using the nginx package. The provided data does not identify specific affected package versions or configurations.

Q: What is known about exploitation requirements?

The severity vector indicates network reachability, no required privileges, no user interaction, and high impact to confidentiality, integrity, and availability. It also indicates high attack complexity; the provided data does not specify the exact request or configuration conditions needed.

Q: Is a default nginx configuration known to be vulnerable?

No. The provided data does not state whether either issue affects default configurations. One issue is described as involving an alias with a rewrite that references $request_filename, which suggests configuration-dependent conditions.

Q: How can administrators determine whether they are affected?

Identify Rocky Linux hosts running nginx and compare their installed package status against the security update referenced by RLSA-2026:98671. The supplied data does not include fixed package versions or detection indicators.
