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...

CVE-2021-47340

In the Linux kernel, the following vulnerability has been resolved: jfs: fix GPF in diFree Avoid passing inode with JFSSBIinode-isb-ipimap == NULL to diFree1. GFP will appear: struct inode ipimap = JFSSBIip-isb-ipimap; struct inomap imap = JFSIPipimap-iimap; JFSIP will return invalid pointer when...
