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 26 Oct 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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 patch is available and should be applied to affected linux-azure kernel versions. The vendor advisory confirms that this issue has been resolved. Users should update to the fixed kernel versions listed in the affectedVersions field to remediate this vulnerability.

Description

A use-after-free (UAF) and memory leak vulnerability was identified and fixed in the Linux kernel's media: atomisp: gc2235 driver. The issue arises from improper error handling in the gc2235_probe() function, where certain failure paths lead to freeing resources prematurely or leaking memory. This can cause instability or unintended behavior in the affected kernel versions. The vulnerability has been patched in specific linux-azure kernel versions.

Impact

This vulnerability can cause use-after-free conditions and memory leaks in the Linux kernel's media subsystem, potentially leading to system instability or crashes. There is no indication of remote exploitation or privilege escalation from the provided data. The severity is assessed as low.

Summary

The Linux kernel's media: atomisp: gc2235 driver contained a vulnerability due to incorrect error path handling in the gc2235_probe() function. If media_entity_pads_init() fails, gc2235_remove() is called, which frees the device but then continues to atomisp_register_i2c_module(), causing a use-after-free condition. Additionally, if atomisp_register_i2c_module() fails, initialized media entities and control handlers are leaked. The gc2235_remove() function calls cleanup functions unconditionally, but these are not always initialized, leading to improper resource management. The fix replaces gc2235_remove() calls in probe error paths with explicit unwind labels that free only the resources initialized at each failure point in reverse order.
