CVE-2026-89618: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: eventfs: Initialize ei->children and ei->list in init_ei() eventfs_create_dir() allocates the eventfs_inode and initializes it with init_ei(). But this does not initialize the eventfs_inode list_heads. If the eventfs_create_dir() fails due to memory pressure, it will call free_ei() before it initialized the lists, and that checks to make sure the eventfs_inode has no children. But because the list wasn't initialized, it will give a false warning. Fix it by moving the list initialization into init_ei(). [ Rewrote change log ]
