—No exploit Fix available

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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 066b90bca755f0b876e7b027b75d1796861d6db0, 0d528a7c421b1f1772fc1d29370b3b5fc0f42b19, 130e3eac51912f2c866e7d035992ede25f8feac0.

Low priority for now. Upgrade to Linux Linux 066b90bca755f0b876e7b027b75d1796861d6db0, 0d528a7c421b1f1772fc1d29370b3b5fc0f42b19, 130e3eac51912f2c866e7d035992ede25f8feac0 or later.

In the Linux kernel, the following vulnerability has been resolved: ACPI: EC: Fix oops when removing custom query handlers When removing custom query handlers, the handler might still be used inside the EC query workqueue, causing a kernel oops if the module holding the callback function was already unloaded. Fix this by flushing the EC query workqueue when removing custom query handlers. Tested on a Acer Travelmate 4002WLMi
