Description
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.
