NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by Centos.

In the Linux kernel, the following vulnerability has been resolved:

fs: fix UAF/GPF bug in nilfs_mdt_destroy

In alloc_inode, inode_init_always() could return -ENOMEM if security_inode_alloc() fails, which causes inode->i_private uninitialized. Then nilfs_is_metadata_file_inode() returns true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(), which frees the uninitialized inode->i_private and leads to crashes(e.g., UAF/GPF).

Fix this by moving security_inode_alloc just prior to this_cpu_inc(nr_inodes)
