CVE-2024-27046
Published: May 2, 2024Last modified: May 2, 2024
Description
In the Linux kernel, the following vulnerability has been resolved: nfp: flower: handle acti_netdevs allocation failure The kmalloc_array() in nfp_fl_lag_do_work() will return null, if the physical memory has run out. As a result, if we dereference the acti_netdevs, the null pointer dereference bugs will happen. This patch adds a check to judge whether allocation failure occurs. If it happens, the delayed work will be rescheduled and try again.
