In the Linux kernel, the following vulnerability has been resolved: jfs: fix GPF in diFree Avoid passing inode with JFSSBI(inode->isb)->ipimap == NULL to diFree()[1]. GFP will appear: struct inode *ipimap = JFSSBI(ip->isb)->ipimap; struct inomap *imap = JFSIP(ipimap)->iimap; JFSIP() will return invalid pointer when ipimap == NULL Call Trace: diFree+0x13d/0x2dc0 fs/jfs/jfsimap.c:853 [1] jfsevictinode+0x2c9/0x370 fs/jfs/inode.c:154 evict+0x2ed/0x750 fs/inode.c:578 iput_final fs/inode.c:1654 [inline] iput.part.0+0x3fe/0x820 fs/inode.c:1680 iput+0x58/0x70 fs/inode.c:1670
