Rocky Linux administrators should apply three new security patches to address vulnerabilities in widely used system libraries and utilities. Two of these advisories target the libcap package, with separate fixes released for both version 9 and version 10 of the operating system. The remaining update focuses on sudo within the Rocky Linux 9 environment to close potential security gaps.
