CVE-2025-37968: iio: light: opt3001: fix deadlock due to concurrent flag access

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 1d7def97e7eb65865ccc01bbdf4eb9e6bbe8a5b5, 2c95c8f0959d0a72575eabf2ff888f47ed6d8b77, 748ebd8e61d0bc182c331b8df3887af7285c8a8f.

Low priority for now. Upgrade to Linux Linux 1d7def97e7eb65865ccc01bbdf4eb9e6bbe8a5b5, 2c95c8f0959d0a72575eabf2ff888f47ed6d8b77, 748ebd8e61d0bc182c331b8df3887af7285c8a8f or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: light: opt3001: fix deadlock due to concurrent flag access The threaded IRQ function in this driver is reading the flag twice: once to lock a mutex and once to unlock it. Even though the code setting the flag is designed to prevent it, there are subtle cases where the flag could be true at the mutex_lock stage and false at the mutex_unlock stage. This results in the mutex not being unlocked, resulting in a deadlock. Fix it by making the opt3001_irq() code generally more robust, reading the flag into a variable and using the variable value at both stages.
