Priority (0–325)
The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

Exploit maturity
An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.
Read in glossary- no public PoC known
KEV status
The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

Classification under NIS2 and CRA
Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.
NIS2
NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.
Read in glossary- Handle the vulnerability in regular vulnerability handling under Art. 21(2)(e) NIS2.
CRA
The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.
Read in glossary- From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.
ISO/IEC 27001
ISO/IEC 27001 is the internationally leading standard for an information security management system (ISMS). It describes a risk-based, process-oriented framework to systematically plan, implement, review and improve information security.

Description
- rebase onto Oracle 1.10.4-2.0.3.el7, which brings the vendor's own backports as Patch1001-Patch1005
- drop 3 of the 4 TuxCare CVE backports in favour of the vendor's copies
- CVE-2024-47615: carry the two halves of our backport the vendor omits. Its
Patch1003 adds the bounds guards to gst_parse_vorbis_setup_packet() but
leaves the function declared void, so the five
return -1statements it writes are discarded and is_header_vorbis() still reports a malformed vorbis setup packet as a valid header; and it guards only against underrunning the ogg packet, where ours also stopped both advance loops from running past op->packet + op->bytes - CVE-2024-47607: the vendor's Patch1001 bounds the write into the caller's pos[64] but not the two memcpys in gst_opus_dec_negotiate(), which copy n_channels entries - up to 255 from the Opus ID header - into the 64-entry dec->opus_pos; take upstream 178ae5ac, which drops the positions above 64 channels
- 1004-video-info-Sanity-check-the-frame-size-to.patch carries no CVE reference in the vendor's commit message; it is taken as a hardening change, with upstream 3d7a5666 on top so its overflow guard stops overflowing itself
