A report says Ubuntu has not released fixed kernel packages for CVE-2026-98432 for Ubuntu 22.04, 24.04 or 26.04, despite the vulnerability’s CVSS 9.8 score. The report says no repair timeline has been announced; the vulnerability’s technical details and the basis for describing it as remote code execution are not established in the supplied material.
Ubuntu 22.04, 24.04 and 26.04 do not yet have fixed kernel packages for CVE-2026-98432, according to a report from freenode news, which says the vulnerability is rated CVSS 9.8. The report says Ubuntu has not announced when patches will be available, leaving administrators of the named releases without an official kernel update for this issue.
The report says that no patched kernels are available for Ubuntu 22.04, 24.04 or 26.04. It describes the issue as a critical vulnerability and says operators using those versions have no vendor-provided kernel package that addresses it. The supplied source does not include an Ubuntu security advisory or a direct statement from Canonical confirming the package status.
The headline characterizes the vulnerability as a zero-day remote code execution flaw, but the material provided does not explain the vulnerability mechanism, affected kernel components, prerequisites for exploitation or whether attacks have been observed. Those details cannot be independently established from the supplied report alone. The CVSS 9.8 score is a severity rating, not proof that exploitation is occurring or that every Ubuntu installation is equally exposed.
According to the report, Ubuntu has given no estimated release date. It says administrators may have to decide whether to keep using stock kernels, apply any available out-of-tree mitigation, or move workloads to a kernel or release that is confirmed to contain a fix. The report does not identify a verified alternative kernel or mitigation, so those options should not be read as confirmed remedies.
Kernel Gap Raises Exposure Concerns
The reported absence of an official fix matters because kernel vulnerabilities can affect the shared foundation on which applications and services run. The source singles out internet-facing systems and multi-tenant hosts, where a flaw affecting kernel security boundaries could have consequences beyond a single application. The actual reach of this specific vulnerability, however, depends on technical details not included in the report.
For system operators, the immediate issue is an uncertain patch timeline. Organizations that standardize on Ubuntu LTS kernels may need to review exposure, monitor Ubuntu’s security notices and weigh operational risks before changing kernels or applying unverified workarounds. A high CVSS score signals serious potential severity, but it does not by itself establish that a host is exploitable over the network or that an attack has succeeded.

Three Ubuntu LTS Releases Named
The report identifies Ubuntu 22.04, 24.04 and 26.04 as lacking fixed kernels for CVE-2026-98432. It frames the issue as a delay of almost three weeks, but the source material does not provide the original disclosure date, the date Ubuntu was notified, or a precise timestamp for its status check. The timing should therefore be understood as the report’s characterization rather than a fully documented patch timeline.
Ubuntu LTS versions are used by organizations seeking a stable operating-system base and long-term maintenance. In this case, the report’s central claim is narrow: affected releases do not have an official kernel package that closes this particular vulnerability. It does not establish whether other Ubuntu releases, upstream Linux kernels or third-party distributions have fixes, nor whether any available package is compatible with the named releases.
““No patched kernels are available yet for 22.04, 24.04, or 26.04 despite a CVSS 9.8 rating.””

Exploit Details and Fix Timing
The supplied material does not include Ubuntu’s own advisory, a technical description of CVE-2026-98432, or confirmation of active exploitation. It also does not document the score’s source or explain the conditions behind the headline’s remote-code-execution characterization. Until those details are available, readers should distinguish the report’s claims from independently confirmed technical facts.
It is also unclear whether temporary mitigations exist, which kernel builds are affected, whether the vulnerability is reachable remotely in typical configurations, and whether a fix has been prepared but not released. The report names three Ubuntu versions but does not provide package identifiers, affected kernel versions, or a list of systems that can be considered unaffected.
Watch for Ubuntu Security Advisories
Administrators should follow Ubuntu security notices and package updates for their installed releases to check whether Canonical publishes a fixed kernel or further technical guidance. The source gives no release schedule, so it does not support a prediction about when an update will arrive. Any mitigation decision should be based on verified vendor guidance and the operator’s assessment of affected systems, rather than assuming that a workaround is available.
The next key developments are an official Ubuntu status statement, details describing the affected kernel configurations, and confirmation of fixed package versions. Until those appear, the reported lack of patches and the absence of an ETA remain the main confirmed points in the supplied material.
Key Questions
Which Ubuntu releases does the report say are affected?
It names Ubuntu 22.04, 24.04 and 26.04 as releases without patched kernels for CVE-2026-98432. The supplied material does not list specific kernel package versions.
How severe is CVE-2026-98432 reported to be?
The report gives the vulnerability a CVSS score of 9.8. That indicates a high severity rating, but the source material does not identify the scoring authority or provide the technical basis for the score.
Is there confirmation that attackers are exploiting the vulnerability?
No evidence of active exploitation is included in the supplied report. It also does not provide enough technical detail to independently verify the remote-code-execution description in the headline.
When will Ubuntu release a patch?
The report says Ubuntu has not announced an ETA. A release date is not available in the source material.
What should administrators do while waiting?
The report describes choices including continuing with the stock kernel, using an out-of-tree mitigation if one exists, or moving workloads to a kernel that has the patch. It does not confirm that any specific workaround or patched alternative is available, so administrators should check vendor guidance before changing systems.
