| Use after free in Windows Modern Device Management (MDM) allows an authorized attacker to elevate privileges locally. |
| Double free in Windows Kerberos allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Kerberos allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Graphics Kernel allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix the reception of a reply packet before data transmission
Fix rxrpc_receiving_reply() to handle the reception of an apparent reply
DATA packet before rxrpc has had a chance to send any request DATA packets
on a client call by checking to see if the call has been exposed yet by
sending the first packet.
Without this, rxrpc_rotate_tx_window() might oops.
Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by
changing the do...while loop into a while loop, just in case a call is
abnormally terminated by an early reply before the last request packet is
transmitted. |
| Use after free in Windows Schannel allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows LDAP - Lightweight Directory Access Protocol allows an unauthorized attacker to execute code over a network. |
| Use after free in Microsoft QUIC allows an unauthorized attacker to execute code over a network. |
| Use after free in Active Directory Certificate Services (AD CS) allows an authorized attacker to execute code over a network. |
| Remote Code Execution in Windows Routing and Remote Access Service (RRAS) allows attacker to gain an unauthorized access to victim's machine |
| Double free in Windows Secure Socket Tunneling Protocol (SSTP) allows an unauthorized attacker to execute code over a network. |
| Use after free in Capability Access Management Service (camsvc) allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Deployment Services allows an unauthorized attacker to execute code over a network. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Backup Engine allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| Use after free in Desktop Window Manager allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix race in unix socket mediation when peer_path is used
The holding a reference to the peer_sk is not enough to ensure access
to the peer sk path. Accessing the path outside of the state lock
allows for a race with unix_release_sock(). Fix this by taking the
state lock and getting a reference to the path under lock.
Ideally for connected sockets we would cache this information so we
don't have to take the lock here. But for now just fix the race. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: Fix lack of locking around modifications of net->cells_dyn_ino
Fix the lack of locking around modifications of net->cells_dyn_ino by
taking net->cells_lock exclusively. This also requires to cell to be
removed from net->cells_dyn_ino in afs_destroy_cell_work() rather than in
afs_cell_destroy() as the latter runs in RCU cleanup context and sleeping
locks cannot be taken there. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: fix use-after-free in ump_to_endpoint()
create_midi2_ump() registers a card-owned snd_ump_endpoint and stores a
back-pointer to its per-interface snd_usb_midi2_ump object in
ump->private_data, but it never installs an ump->private_free hook and
never clears that pointer.
If a later step of snd_usb_midi_v2_create() fails, its error path calls
free_all_midi2_umps(), which kfree()s the snd_usb_midi2_ump object while
the already-registered endpoint keeps pointing at it. The created
/dev/snd/umpC*D* node stays exposed, so the first operation of any UMP
open, ump_to_endpoint(), dereferences the dangling ump->private_data and
reads rmidi->eps[dir] out of freed memory.
A malicious USB MIDI 2.0 device that makes creation fail after the
endpoint is registered can thus trigger a slab use-after-free read on a
subsequent open of the UMP node.
Clear the endpoint's back-pointer before freeing the object, and let
ump_to_endpoint() tolerate a NULL private_data so the open/close/trigger
callbacks fail cleanly (their callers already handle a NULL endpoint)
instead of dereferencing a stale pointer.

| In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_dp: Switch to drmm_kzalloc()
Driver makes use of drmm_encoder_init() to initialize the encoder and
automatically handle the cleanup by registering drm_encoder_cleanup()
with drmm_add_action().
However, the internal structure containing the encoder part gets
allocated with devm_kzalloc(), which happens while component_bind_all()
is being called from Rockchip DRM driver. The component framework
further ensures it is deallocated as part of releasing all the resources
claimed during bind, which is triggered from component_unbind_all().
When the reference to the DRM device gets eventually dropped via
drm_dev_put() in rockchip_drm_unbind(), drmm_encoder_alloc_release()
attempts to access the now released encoder structure, leading to
use-after-free.
Ensure driver's internal structure is still reachable on encoder cleanup
by switching from a device-managed allocation to a drm-managed one. |
