19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: dm: fix a crash if blk_alloc_disk fails If blk_alloc_disk fails, the variable md->disk is set to an error value. cleanup_mapped_device will see that md->disk is non-NULL and it will attempt to access it, causing a crash on this statement "md->disk->private_data = NULL;". • https://git.kernel.org/stable/c/d7aec2a06730b774a97caaf48cbbc58330a85829 •
CVE-2024-50273 – btrfs: reinitialize delayed ref list after deleting it from the list

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: reinitialize delayed ref list after deleting it from the list At insert_delayed_ref() if we need to update the action of an existing ref to BTRFS_DROP_DELAYED_REF, we delete the ref from its ref head's ref_add_list using list_del(), which leaves the ref's add_list member not reinitialized, as list_del() sets the next and prev members of the list to LIST_POISON1 and LIST_POISON2, respectively. If later we end up calling drop_delaye... • https://git.kernel.org/stable/c/1d57ee941692d0cc928526e21a1557b2ae3e11db •
CVE-2024-50272 – filemap: Fix bounds checking in filemap_read()
https://notcve.org/view.php?id=CVE-2024-50272
19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: filemap: Fix bounds checking in filemap_read() If the caller supplies an iocb->ki_pos value that is close to the filesystem upper limit, and an iterator with a count that causes us to overflow that limit, then filemap_read() enters an infinite loop. This behaviour was discovered when testing xfstests generic/525 with the "localio" optimisation for loopback NFS mounts. • https://git.kernel.org/stable/c/c2a9737f45e27d8263ff9643f994bda9bac0b944 •
