https://notcve.org/view.php?id=CVE-2023-53137
02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: Fix possible corruption when moving a directory When we are renaming a directory to a different directory, we need to update '..' entry in the moved directory. However nothing prevents moved directory from being modified and even converted from the inline format to the normal format. When such race happens the rename code gets confused and we crash. Fix the problem by locking the moved directory. In the Linux kernel, the following vul... • https://git.kernel.org/stable/c/32f7f22c0b52e8189fef83986b16dc7abe95f2c4 •

02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: af_unix: fix struct pid leaks in OOB support syzbot reported struct pid leak [1]. Issue is that queue_oob() calls maybe_add_creds() which potentially holds a reference on a pid. But skb->destructor is not set (either directly or by calling unix_scm_to_skb()) This means that subsequent kfree_skb() or consume_skb() would leak this reference. In this fix, I chose to fully support scm even for the OOB message. [1] BUG: memory leak unreferenced ... • https://git.kernel.org/stable/c/314001f0bf927015e459c9d387d62a231fe93af3 •
