CVSS v3.1 |
| Improper access control in asset contact password in Devolutions Server 2026.3.8.0 and earlier allows an authenticated user with general Edit but without Edit asset permission to modify the asset contact password via a crafted direct request to the partial-save endpoint. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: dummy-hcd: Fix wait for outstanding request completions
The dummy-hcd driver emulates synchronize_irq() by waiting until its
private callback_usage counter drops to 0 (with the private lock not
held). This counter is incremented whenever a gadget driver callback
occurs (which requires the private lock to be dropped), but not when a
request completion handler is called.
This is an oversight. Request completion is triggered by timer
interrupts (emulating device IRQs in a real UDC), and the interrupt
handlers are supposed to have completed when the synchronize_irq()
emulation routine returns -- they aren't supposed to be in the middle
of a completion callback. If this happens it can lead to a gadget
driver's unbind routine running before all outstanding request
completions have finished, maybe even allowing the gadget driver's
module to be unloaded while a completion handler is still running.
Fix the oversight by incrementing the callback_usage value across
request completion callbacks. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: aspeed-vhub: cancel wake work on device removal
wake_work is armed from the gadget .wakeup callback to resume suspended
downstream ports, and it is never cancelled in ast_vhub_remove(), so a
work item queued before or during removal can run after devm has freed
vhub and its ports, a use-after-free.
Cancelling the work alone is not sufficient: usb_gadget_wakeup() takes
no lock and the unbind path never clears wakeup_en, so a remote-wakeup
request in flight on another CPU can re-arm the work after the cancel
and before vhub is freed.
ast_vhub_del_dev() already clears d->registered under vhub->lock before
unregistering the gadget. Refuse the wakeup in ast_vhub_udc_wakeup()
once d->registered is clear: the check and the schedule_work() are then
atomic against the unbind, so a wakeup that passed before the flag was
cleared is drained by the cancel_work_sync() after the del_dev loop,
and one that arrives later returns without arming. Also move INIT_WORK()
to the top of ast_vhub_probe(), since the probe error path reuses
ast_vhub_remove() and would otherwise cancel a never-initialized work
item.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_uac1_legacy: validate bRequest index in generic_{set,get}_cmd
generic_set_cmd() and generic_get_cmd() use the low nibble of
ctrl->bRequest as an index into con->data[]:
u8 cmd = (ctrl->bRequest & 0x0F); /* 0 .. 15 */
...
con->data[cmd] = value; /* OOB when cmd >= 5 */
struct usb_audio_control (include/linux/usb/audio.h) declares data as
a 5-element array, so indices 5 through 15 write (or read) up to 44
bytes past the end of the array on the heap.
A malicious USB host can craft a class-specific SET_CUR / GET_CUR
request with an arbitrary bRequest value, triggering the out-of-bounds
access from an IRQ completion handler with no further preconditions.
Add an ARRAY_SIZE() guard to both functions. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: midi2: Fix the jack descriptor array sizes
The jack in/out descriptor arrays in struct f_midi2_usb_config have
the size of MAX_CABLES, which look reasonable -- but it turned out to
be incorrect. Namely, the entries for those arrays are added from
both inputs and outputs, hence for each loop cycle, it adds two, ended
up with as twice as the expected size. This inconsistency may result
in potential OOB when a large number of jacks are set up via configfs,
although the max number of cables (the loop count) is limited to
MAX_CABLES.
For addressing it, correct the jack_ins & jack_outs array sizes to
twice, MAX_CABLES * 2. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: storage: sierra_ms: reject short SWoC info transfers
sierra_get_swoc_info() requests sizeof(struct swoc_info) (60) bytes
from the device via usb_control_msg(), but its callers only treat a
negative return value as failure. A device that answers the
vendor-specific GetSwocInfo request with a short IN transfer is
therefore accepted, leaving the tail of the freshly allocated
(kmalloc(), non-zeroing) swoc_info buffer uninitialized.
truinst_show() subsequently prints swocInfo->rev, swocInfo->LinuxSKU
and swocInfo->LinuxVer from that buffer into the world-readable
(0444) "truinst" sysfs attribute. An emulated/malicious USB device
(VID 0x1199, PID 0x0fff) can exploit this to disclose up to 5 bytes
of stale kernel heap memory (kmalloc-64) to unprivileged userspace,
once per sysfs read, indefinitely. On kernels built without
init_on_alloc this leaks recently freed heap contents.
Only accept the transfer when the full structure was received.
sierra_ms_init() already retries failed queries, so well-behaved
devices are unaffected. |

md/raid5: let stripe batch bm_seq comparison wrap-safe
Once the 32-bit seq wraps, a newer bm_seq can look smaller
than old, so .. covert to wrap-safe calculate way. |
| In the Linux kernel, the following vulnerability has been resolved:

This bug showed up starting with v7.3-rc1. At the NIP in
phy_link_topo_add_phy() is a netdev_need_ops_lock() check.
This was added by the following
commit ded86da4bbb7 ("net: ethtool: relax ethnl_req_get_phydev() locking assertion")
The bug shows up because at the time of_phy_connect() was called, the
netdev_ops were *not yet* determined. My fix is to move the code that
sets netdev_ops+commac.ops+ethtool_ops further up as emac_init_config()
derives that by looking at the device-tree and sets the required
dev->phy_mode accordingly.
During review, the Sashiko bot's AI stated that the commac assignment
became a dead store. Great catch! To keep the original behavior as-is,
one mentioned option "set dev->commac.ops = &emac_commac_ops only in
the non-gige case?" sounded like a great plan. So the dev->commac.ops
assignment for the non-gige-case moves into the else block.
This patch was tested on a WD MyBook Live (RGMII). the device now works again. |
