CVE-2021-47340

CVE-2021-47340 is a Linux kernel vulnerability in the JFS subsystem. The issue arises when diFree() processes an inode without a valid ipimap, causing a NULL dereference via JFS_IP(ipimap) and leading to a GFP-related fault. The fix prevents passing an inode with IPIMAP == NULL to diFree, avoidin...
