In the Linux kernel, the following vulnerability has been resolved:
jfs: fix GPF in diFree
Avoid passing inode with
JFS_SBI(inode->i_sb)->ipimap == NULL to
diFree()[1]. GFP will appear:
struct inode *ipimap = JFS_SBI(ip->i_sb)->ipimap;
struct inomap *imap = JFS_IP(ipimap)->i_imap;
JFS_IP() will return invalid pointer when ipimap == NULL
