Descriptions

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

jfs: fix uaf in jfs_evict_inode

When the execution of diMount(ipimap) fails, the object ipimap that has been
released may be accessed in diFreeSpecial(). Asynchronous ipimap release occurs
when rcu_core() calls jfs_free_node().

Therefore, when diMount(ipimap) fails, sbi->ipimap should not be initialized as
ipimap.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: jfs: corrige uaf en jfs_evict_inode Cuando falla la ejecución de diMount(ipimap), se puede acceder al objeto ipimap que se ha liberado en diFreeSpecial(). La liberación asincrónica de ipimap ocurre cuando rcu_core() llama a jfs_free_node(). Por lo tanto, cuando falla diMount(ipimap), sbi->ipimap no debe inicializarse como ipimap.
