CVE-2026-68413: wifi: ipw2100: fix potential memory leak in ipw2100_pci_init_one()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 0d388f62031dbabcba0f44bb91b59f10e88cac17, 71614326ab43e8b8f392ba865aeb6d7e327dff7d, 768a701362a8f77b62c14f8202ad559b7ecbb0c6; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0d388f62031dbabcba0f44bb91b59f10e88cac17, 71614326ab43e8b8f392ba865aeb6d7e327dff7d, 768a701362a8f77b62c14f8202ad559b7ecbb0c6; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: ipw2100: fix potential memory leak in ipw2100_pci_init_one() The memory allocated in the ipw2100_alloc_device() function is not freed in some of the error paths in ipw2100_pci_init_one(). Fix that by converting the direct return into a goto to the error path return. The error path when pci_enable_device() fails cannot jump to fail, since at this point priv is not set, so perform error handling inline.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
