https://notcve.org/view.php?id=CVE-2022-49828
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: hugetlbfs: don't delete error page from pagecache This change is very similar to the change that was made for shmem [1], and it solves the same problem but for HugeTLBFS instead. Currently, when poison is found in a HugeTLB page, the page is removed from the page cache. That means that attempting to map or read that hugepage in the future will result in a new hugepage being allocated instead of notifying the user that the page was poisoned.... • https://git.kernel.org/stable/c/30571f28bb35c826219971c63bcf60d2517112ed •
