| An authenticated attacker can obtain any plant name by knowing the plant ID. |
| Due to lack of server-side input validation, attackers can inject malicious JavaScript code into users personal spaces of the web portal. |
| Unauthenticated attackers can add devices of other users to their scenes (or arbitrary scenes of other arbitrary users). |
| An attacker can export other users' plant information. |
| An unauthenticated attacker can hijack other users' devices and potentially control them. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: steam: Prevent NULL pointer dereference in steam_{recv,send}_report
It is possible for a malicious device to forgo submitting a Feature
Report. The HID Steam driver presently makes no prevision for this
and de-references the 'struct hid_report' pointer obtained from the
HID devices without first checking its validity. Let's change that. |
| Unauthenticated attackers can rename arbitrary devices of arbitrary users (i.e., EV chargers). |

scsi: storvsc: Remove WQ_MEM_RECLAIM from storvsc_error_wq
storvsc_error_wq workqueue should not be marked as WQ_MEM_RECLAIM as it
doesn't need to make forward progress under memory pressure. Marking this
workqueue as WQ_MEM_RECLAIM may cause deadlock while flushing a
non-WQ_MEM_RECLAIM workqueue. In the current state it causes the following
warning:

| In the Linux kernel, the following vulnerability has been resolved:
md: call __md_stop_writes in md_stop
From the link [1], we can see raid1d was running even after the path
raid_dtr -> md_stop -> __md_stop.
Let's stop write first in destructor to align with normal md-raid to
fix the KASAN issue.

| In the Linux kernel, the following vulnerability has been resolved:
xen/privcmd: fix error exit of privcmd_ioctl_dm_op()
The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.
Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.
Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages. |
| An unauthenticated attacker can obtain EV charger version and firmware upgrading history by knowing the charger ID. |
| Unauthenticated attackers can query an API endpoint and get device details. |
| An unauthenticated attackers can obtain a list of smart devices by knowing a valid username through an unprotected API. |
| In the Linux kernel, the following vulnerability has been resolved:
s390: fix double free of GS and RI CBs on fork() failure
The pointers for guarded storage and runtime instrumentation control
blocks are stored in the thread_struct of the associated task. These
pointers are initially copied on fork() via arch_dup_task_struct()
and then cleared via copy_thread() before fork() returns. If fork()
happens to fail after the initial task dup and before copy_thread(),
the newly allocated task and associated thread_struct memory are
freed via free_task() -> arch_release_task_struct(). This results in
a double free of the guarded storage and runtime info structs
because the fields in the failed task still refer to memory
associated with the source task.
This problem can manifest as a BUG_ON() in set_freepointer() (with
CONFIG_SLAB_FREELIST_HARDENED enabled) or KASAN splat (if enabled)
when running trinity syscall fuzz tests on s390x. To avoid this
problem, clear the associated pointer fields in
arch_dup_task_struct() immediately after the new task is copied.
Note that the RI flag is still cleared in copy_thread() because it
resides in thread stack memory and that is where stack info is
copied. |
| Unauthenticated attackers can retrieve full list of users associated with arbitrary accounts. |
| Unauthenticated attackers can retrieve serial number of smart meters associated to a specific user account. |
| An attacker can upload an arbitrary file instead of a plant image. |
