thermal/drivers/rcar: Fix error checking in probe()

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 35bf61798e7d4abf39667d98f298f793b3dd9bbe, 623349a18d4c6e6add7876553c0cb6947c8d92e6, 810875c5996f731961fc5ee1bd24e711f2e8fe78; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1.

Low priority for now. Upgrade to Linux Linux 35bf61798e7d4abf39667d98f298f793b3dd9bbe, 623349a18d4c6e6add7876553c0cb6947c8d92e6, 810875c5996f731961fc5ee1bd24e711f2e8fe78; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/rcar: Fix error checking in probe() This code accidentally calls thermal_zone_device_enable() before checking whether thermal_zone_device_register_with_trips() failed. Move the call until later to avoid an error pointer dereference of "priv->zone". The driver works differently depending on if we are using OF thermal or not. We use thermal_add_hwmon_sysfs() if we are using OF thermal and call thermal_zone_device_enable() if not. We can share same error check for if either of these fail. Moving the thermal_zone_device_enable() call is a bit cleaner as well. The original code used a three step process to cleanup: 1. Call thermal_zone_device_unregister() to cleanup. 2. Set priv->zone to an error pointer to preserve the error code. 3. Set priv->zone to NULL to avoid a second call to thermal_zone_device_unregister() in the rcar_thermal_remove() function. Now we can just do a direct goto error_unregister and rcar_thermal_remove() handles the cleanup properly.
