UBUNTU-CVE-2025-37968: Medium severity ubuntu/linux-aws vulnerability

Q: Who is exposed to this issue?

Systems using the listed Ubuntu Linux kernel packages are in scope if they use the opt3001 light-sensor driver and encounter concurrent IRQ flag access. The affected package families include standard, AWS, Azure, GCP, and FIPS kernel variants.

Q: What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required, but the attack requires the specified additional attack condition.

Q: What is the operational impact?

The failure can leave a mutex locked, causing a deadlock. The severity vector indicates high availability impact, with no indicated impact to confidentiality or integrity.

Q: How can I determine whether my system needs remediation?

Check whether the system is running one of the listed Ubuntu kernel package families and whether the opt3001 driver is in use. The supplied data does not include fixed package versions; consult the Ubuntu CVE advisory for package-status details.

Updated

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 mutexlock stage and false at the mutexunlock stage. This results in the mutex not being unlocked, resulting in a deadlock. Fix it by making the opt3001irq() code generally more robust, reading the flag into a variable and using the variable value at both stages.

Frequently Asked Questions

Who is exposed to this issue?

Systems using the listed Ubuntu Linux kernel packages are in scope if they use the opt3001 light-sensor driver and encounter concurrent IRQ flag access. The affected package families include standard, AWS, Azure, GCP, and FIPS kernel variants.

What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required, but the attack requires the specified additional attack condition.

What is the operational impact?

The failure can leave a mutex locked, causing a deadlock. The severity vector indicates high availability impact, with no indicated impact to confidentiality or integrity.

How can I determine whether my system needs remediation?

Check whether the system is running one of the listed Ubuntu kernel package families and whether the opt3001 driver is in use. The supplied data does not include fixed package versions; consult the Ubuntu CVE advisory for package-status details.
