In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Add error handling in xhci_map_urb_for_dma Currently xhci_map_urb_for_dma() creates a temporary buffer and copies the SG list to the new linear buffer. But if the kzalloc_node() fails, then the following sg_pcopy_to_buffer() can lead to crash since it tries to memcpy to NULL pointer. So return -ENOMEM if kzalloc returns null pointer. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: xhci: agregar manejo de errores en xhci_map_urb_for_dma Actualmente, xhci_map_urb_for_dma() crea un búfer temporal y copia la lista SG en el nuevo búfer lineal. Pero si kzalloc_node() falla, entonces el siguiente sg_pcopy_to_buffer() puede provocar un fallo ya que intenta memcpy al puntero NULL. Entonces devuelve -ENOMEM si kzalloc devuelve un puntero nulo. • https://git.kernel.org/stable/c/2017a1e58472a27e532b9644b4a61dfe18f6baac https://git.kernel.org/stable/c/4a49d24fdec0a802aa686a567a3989a9fdf4e5dd https://git.kernel.org/stable/c/b2c898469dfc388f619c6c972a28466cbb1442ea https://git.kernel.org/stable/c/620b6cf2f1a270f48d38e6b8ce199c1acb3e90f4 https://git.kernel.org/stable/c/962300a360d24c5be5a188cda48da58a37e4304d https://git.kernel.org/stable/c/7b6cc33593d7ccfc3011b290849cfa899db46757 https://git.kernel.org/stable/c/be95cc6d71dfd0cba66e3621c65413321b398052 https://access.redhat.com/security/cve/CVE-2024-26964 •

https://notcve.org/view.php?id=CVE-2024-26963
In the Linux kernel, the following vulnerability has been resolved: usb: dwc3-am62: fix module unload/reload behavior As runtime PM is enabled, the module can be runtime suspended when .remove() is called. Do a pm_runtime_get_sync() to make sure module is active before doing any register operations. Doing a pm_runtime_put_sync() should disable the refclk so no need to disable it again. Fixes the below warning at module removel.

Get rid of the now unnnecessary dwc3_ti_remove_core(). Without this, module re-load doesn't work properly. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: dwc3-am62: corrige el comportamiento de descarga/recarga del módulo. Como el PM en tiempo de ejecución está habilitado, el tiempo de ejecución del módulo se puede suspender cuando se llama a .remove(). Realice pm_runtime_get_sync() para asegurarse de que el módulo esté activo antes de realizar cualquier operación de registro. Hacer pm_runtime_put_sync() debería deshabilitar refclk, por lo que no es necesario deshabilitarlo nuevamente. • https://git.kernel.org/stable/c/e8784c0aec03a2581ee55827ba694e129d6a57ad https://git.kernel.org/stable/c/6c6a45645a2e6a272dfde14eddbb6706de63c25d https://git.kernel.org/stable/c/7dfed9855397d0df4c6f748d1f66547ab3bad766 https://git.kernel.org/stable/c/629b534c42d04f0797980f2d1ed105fdb8906975 https://git.kernel.org/stable/c/3895780fabd120d0fbd54354014e85207b25687c https://git.kernel.org/stable/c/6661befe41009c210efa2c1bcd16a5cc4cff8a06 •
CVSS: 5.5EPSS: 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 https://access.redhat.com/security/cve/CVE-2024-26962 https://bugzilla.redhat.com/show_bug.cgi?id=2278174 •
