https://notcve.org/view.php?id=CVE-2022-49831
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: initialize device's zone info for seeding When performing seeding on a zoned filesystem it is necessary to initialize each zoned device's btrfs_zoned_device_info structure, otherwise mounting the filesystem will cause a NULL pointer dereference. This was uncovered by fstests' testcase btrfs/163. In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: initialize device's zone info for seeding When perf... • https://git.kernel.org/stable/c/91c38504e589dadbcde47b1cacdfc5b684154d44 •

CVE-2022-49830 – drm/drv: Fix potential memory leak in drm_dev_init()
https://notcve.org/view.php?id=CVE-2022-49830
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: drm/drv: Fix potential memory leak in drm_dev_init() drm_dev_init() will add drm_dev_init_release() as a callback. When drmm_add_action() failed, the release function won't be added. As the result, the ref cnt added by device_get() in drm_dev_init() won't be put by drm_dev_init_release(), which leads to the memleak. Use drmm_add_action_or_reset() instead of drmm_add_action() to prevent memleak. unreferenced object 0xffff88810bc0c800 (size 2... • https://git.kernel.org/stable/c/2cbf7fc6718b9443ecd6261308c6348d8ffcccae •

CVE-2022-49828 – hugetlbfs: don't delete error page from pagecache
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 •

CVE-2022-49827 – drm: Fix potential null-ptr-deref in drm_vblank_destroy_worker()

01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: drm: Fix potential null-ptr-deref in drm_vblank_destroy_worker() drm_vblank_init() call drmm_add_action_or_reset() with drm_vblank_init_release() as action. If __drmm_add_action() failed, will directly call drm_vblank_init_release() with the vblank whose worker is NULL. As the resule, a null-ptr-deref will happen in kthread_destroy_worker().
