Description

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)

Affected configurations

• linux linux kernel (< 4.9.331) • linux linux kernel (>= 4.10 < 4.14.296) • linux linux kernel (>= 4.15 < 4.19.262) • linux linux kernel (>= 4.20 < 5.4.218) • linux linux kernel (>= 5.5 < 5.10.148) • linux linux kernel (>= 5.11 < 5.15.73) • linux linux kernel (>= 5.16 < 5.19.15) • linux linux kernel (>= 6.0 < 6.0.1)
