Exploitation evidence

Disclosed: evidence found.
CVE published 9 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 4 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A security update is available that fixes these vulnerabilities in linux-intel-iot-realtime kernel version 5.15.0-1096.98. Users should apply the update via their standard system update process and reboot their systems to activate the fixes. Because of an ABI change, all third-party kernel modules must be recompiled and reinstalled after updating. No additional mitigation steps are required beyond applying the official patch and rebooting.

Description

Multiple vulnerabilities were discovered in the AppArmor Linux kernel Security Module (LSM) and other Linux kernel subsystems affecting the linux-intel-iot-realtime kernel. These flaws could allow an unprivileged local attacker to load, replace, or remove arbitrary AppArmor profiles, potentially causing denial of service, exposure of sensitive kernel memory, local privilege escalation, or container escape. Additional issues affect ARM64 architecture, Cryptographic API, Netfilter, and network traffic control. A security update fixing these issues is available and requires a system reboot and recompilation of third-party kernel modules.
