medium Nessus Plugin ID 375468

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-500574 advisory.

 - ipv4: validate checksum_start before completing checksum (Michael S. Tsirkin) [Orabug: 40165811] {CVE-2026-99999}
 - ipv4: free inet_opt and ireq_opt after an RCU grace period (Eric Dumazet) [Orabug: 40165788] {CVE-2026-98432}
 - exec: Cleanup POSIX timers right after de_thread() (Hyunwoo Kim) [Orabug: 40120750] {CVE-2026-98260}

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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 packages.
