CVSS: 5.5EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26973 – fat: fix uninitialized field in nostale filehandles
https://notcve.org/view.php?id=CVE-2024-26973
In the Linux kernel, the following vulnerability has been resolved: fat: fix uninitialized field in nostale filehandles When fat_encode_fh_nostale() encodes file handle without a parent it stores only first 10 bytes of the file handle. However the length of the file handle must be a multiple of 4 so the file handle is actually 12 bytes long and the last two bytes remain uninitialized. This is not great at we potentially leak uninitialized information with the handle to userspace. Properly initialize the full handle length. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fat: corrige el campo no inicializado en los identificadores de archivos notale Cuando fat_encode_fh_nostale() codifica el identificador de archivo sin un padre, almacena solo los primeros 10 bytes del identificador de archivo. • https://git.kernel.org/stable/c/ea3983ace6b79c96e6ab3d3837e2eaf81ab881e2 https://git.kernel.org/stable/c/9840d1897e28f8733cc1e38f97e044f987dc0a63 https://git.kernel.org/stable/c/f52d7663a10a1266a2d3871a6dd8fd111edc549f https://git.kernel.org/stable/c/a276c595c3a629170b0f052a3724f755d7c6adc6 https://git.kernel.org/stable/c/b7fb63e807c6dadf7ecc1d43448c4f1711d7eeee https://git.kernel.org/stable/c/c8cc05de8e6b5612b6e9f92c385c1a064b0db375 https://git.kernel.org/stable/c/03a7e3f2ba3ca25f1da1d3898709a08db14c1abb https://git.kernel.org/stable/c/74f852654b8b7866f15323685f1e178d3 •

CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-26962 – dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape
https://notcve.org/view.php?id=CVE-2024-26962
In the Linux kernel, the following vulnerability has been resolved: dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape For raid456, if reshape is still in progress, then IO across reshape position will wait for reshape to make progress. However, for dm-raid, in following cases reshape will never make progress hence IO will hang: 1) the array is read-only; 2) MD_RECOVERY_WAIT is set; 3) MD_RECOVERY_FROZEN is set; After commit c467e97f079f ("md/raid6: use valid sector values to determine if an I/O should wait on the reshape") fix the problem that IO across reshape position doesn't wait for reshape, the dm-raid test shell/lvconvert-raid-reshape.sh start to hang: [root@fedora ~]# cat /proc/979/stack [<0>] wait_woken+0x7d/0x90 [<0>] raid5_make_request+0x929/0x1d70 [raid456] [<0>] md_handle_request+0xc2/0x3b0 [md_mod] [<0>] raid_map+0x2c/0x50 [dm_raid] [<0>] __map_bio+0x251/0x380 [dm_mod] [<0>] dm_submit_bio+0x1f0/0x760 [dm_mod] [<0>] __submit_bio+0xc2/0x1c0 [<0>] submit_bio_noacct_nocheck+0x17f/0x450 [<0>] submit_bio_noacct+0x2bc/0x780 [<0>] submit_bio+0x70/0xc0 [<0>] mpage_readahead+0x169/0x1f0 [<0>] blkdev_readahead+0x18/0x30 [<0>] read_pages+0x7c/0x3b0 [<0>] page_cache_ra_unbounded+0x1ab/0x280 [<0>] force_page_cache_ra+0x9e/0x130 [<0>] page_cache_sync_ra+0x3b/0x110 [<0>] filemap_get_pages+0x143/0xa30 [<0>] filemap_read+0xdc/0x4b0 [<0>] blkdev_read_iter+0x75/0x200 [<0>] vfs_read+0x272/0x460 [<0>] ksys_read+0x7a/0x170 [<0>] __x64_sys_read+0x1c/0x30 [<0>] do_syscall_64+0xc6/0x230 [<0>] entry_SYSCALL_64_after_hwframe+0x6c/0x74 This is because reshape can't make progress. For md/raid, the problem doesn't exist because register new sync_thread doesn't rely on the IO to be done any more: 1) If array is read-only, it can switch to read-write by ioctl/sysfs; 2) md/raid never set MD_RECOVERY_WAIT; 3) If MD_RECOVERY_FROZEN is set, mddev_suspend() doesn't hold 'reconfig_mutex', hence it can be cleared and reshape can continue by sysfs api 'sync_action'. However, I'm not sure yet how to avoid the problem in dm-raid yet. This patch on the one hand make sure raid_message() can't change sync_thread() through raid_message() after presuspend(), on the other hand detect the above 3 cases before wait for IO do be done in dm_suspend(), and let dm-raid requeue those IO. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dm-raid456, md/raid456: soluciona un punto muerto para dm-raid456 mientras io concurre con reshape. Para raid456, si el reshape todavía está en progreso, entonces IO en la posición de reshape esperará remodelar para progresar. • https://git.kernel.org/stable/c/5943a34bf6bab5801e08a55f63e1b8d5bc90dae1 https://git.kernel.org/stable/c/a8d249d770cb357d16a2097b548d2e4c1c137304 https://git.kernel.org/stable/c/41425f96d7aa59bc865f60f5dda3d7697b555677 •
