CVE-2024-35806 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: soc: fsl: qbman: Always disable interrupts when taking cgr_lock smp_call_function_single disables IRQs when executing the callback. To prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. This is already done by qman_update_cgr and qman_delete_cgr; fix the other lockers.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
