CVE-2025-39709 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: media: venus: protect against spurious interrupts during probe Make sure the interrupt handler is initialized before the interrupt is registered. If the IRQ is registered before hfi_create(), it's possible that an interrupt fires before the handler setup is complete, leading to a NULL dereference. This error condition has been observed during system boot on Rb3Gen2.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
