Descriptions

In the Linux kernel, the following vulnerability has been resolved:

mm/slub: fix to return errno if kmalloc() fails

In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to
out-of-memory, if it fails, return errno correctly rather than
triggering panic via BUG_ON();

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm/slub: corrección para devolver errno si kmalloc() falla. En create_unique_id(), kmalloc(, GFP_KERNEL) puede fallar debido a falta de memoria, si falla, regrese errno correctamente en lugar de provocar pánico mediante BUG_ON(); ¡ERROR del kernel en mm/slub.c:5893!
