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: NULL Pointer Dereference

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...

Vulnerability of the diFree function (fs/jfs/jfs_imap.c) in the Linux operating system, allowing a local attacker to execute arbitrary code

The vulnerability of the diFree function fs/jfs/jfsimap.c in the jfs file system of the Linux operating system is related to the use of memory after it is freed during a mount failure. Exploiting this vulnerability allows an attacker acting locally to execute arbitrary code...
