Ubuntu vendor package status

Canonical’s release and source-package findings are shown separately from local repository availability.

01

What, why and how

In the Linux kernel, the following vulnerability has been resolved: PCI: Free released resource after coalescing release_resource() doesn't actually free the resource or resource list entry so free the resource list entry to avoid a leak.

What

In the Linux kernel, the following vulnerability has been resolved: PCI: Free released resource after coalescing release_resource() doesn't actually free the resource or resource list entry so free the resource list entry to avoid a leak.

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through the affected interface may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
the affected interface → vulnerable operation → cause the confidentiality, integrity or availability impact described by the vendor
