- Summary
- CVE-2024-39494 affecting package kernel for versions less than 5.15.176.3-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ima: Fix use-after-free on a dentry's dname.name
->dname.name can change on rename and the earlier value can be freed; there are conditions sufficient to stabilize it (->dlock on dentry, ->dlock on its parent, ->irwsem exclusive on the parent's inode, rename_lock), but none of those are met at any of the sites. Take a stable snapshot of the name instead.
