CVE-2025-40107: can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled

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: 0.19% (FIRST EPSS).
  • Fixed version: Linux Linux 1d2ef21f02baff0c109ad78b9e835fb4acb14533, 6b696808472197b77b888f50bc789a3bae077743, d1fc4c041459e2d4856c1b2501486ba4f0cbf96b; azl3 kernel 6.6.104.2-4 on Azure Linux 3.0 6.6.112.1-2.

Low priority for now. Upgrade to Linux Linux 1d2ef21f02baff0c109ad78b9e835fb4acb14533, 6b696808472197b77b888f50bc789a3bae077743, d1fc4c041459e2d4856c1b2501486ba4f0cbf96b; azl3 kernel 6.6.104.2-4 on Azure Linux 3.0 6.6.112.1-2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled This issue is similar to the vulnerability in the `mcp251x` driver, which was fixed in commit 03c427147b2d ("can: mcp251x: fix resume from sleep before interface was brought up"). In the `hi311x` driver, when the device resumes from sleep, the driver schedules `priv->restart_work`. However, if the network interface was not previously enabled, the `priv->wq` (workqueue) is not allocated and initialized, leading to a null pointer dereference. To fix this, we move the allocation and initialization of the workqueue from the `hi3110_open` function to the `hi3110_can_probe` function. This ensures that the workqueue is properly initialized before it is used during device resume. And added logic to destroy the workqueue in the error handling paths of `hi3110_can_probe` and in the `hi3110_can_remove` function to prevent resource leaks.
