CVE-2024-27046

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-27046
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfp: flor: manejar el error de asignación de acti_netdevs El kmalloc_array() en nfp_fl_lag_do_work() devolverá nulo, si la memoria física se ha agotado. Como resultado, si eliminamos la referencia a acti_netdevs, se producirán errores de desreferencia del puntero nulo. Este parche agrega una verificación para juzgar si se produce una falla en la asignación. Si esto sucede, el trabajo retrasado se reprogramará y se intentará nuevamente.
