CVE-2026-98662: iio: light: gp2ap020a00f: drain irq_work after free_irq

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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 43fbbb9eaae5d6f45668e3c4d45508c498d6ba9c, 63213927b141085b6c8719b8037dab3074b7e0fe, 6f2bb000493c3b4f5715b3103657393672aea05b; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.

Low priority for now. Upgrade to Linux Linux 43fbbb9eaae5d6f45668e3c4d45508c498d6ba9c, 63213927b141085b6c8719b8037dab3074b7e0fe, 6f2bb000493c3b4f5715b3103657393672aea05b; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: light: gp2ap020a00f: drain irq_work after free_irq The threaded IRQ handler queues data->work through irq_work_queue() so the trigger is polled from a per-CPU context. free_irq() does not flush an irq_work the handler already queued, so after gp2ap020a00f_remove() returns that work may still run and call iio_trigger_poll() on data->trig, which the devm cleanup has already freed, causing a use-after-free. Add irq_work_sync(&data->work) after free_irq() in remove() and in the probe error path, mirroring commit 78601726d4a5 ("iio: trigger: sysfs: fix use-after-free on remove"). Found by an in-house static analysis tool, confirmed by manual review.
