Rocky Linux 9.6 [TuxCare] Security Update: grafana-pcp Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1779109358)

high Nessus Plugin ID 351678

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1779109358 advisory.

 - During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls. (CVE-2026-32280)

 - If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3. (CVE-2026-32283)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected grafana-pcp package based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1779109358.
