| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Push Notifications allows an authorized attacker to elevate privileges locally. |
| 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:
sunrpc: pin svc_xprt across the asynchronous TLS handshake callback
svc_tcp_handshake() stores the raw svc_xprt pointer in
tls_handshake_args.ta_data and submits the request through
tls_server_hello_x509(). The handshake core takes only
sock_hold(req->hr_sk); nothing references the embedding struct
svc_sock that svc_tcp_handshake_done() reaches via container_of().
Two close races leave the in-flight callback writing through a freed
svc_sock. svc_sock_free() calls tls_handshake_cancel() and discards
its return value: a false return means handshake_complete() has
already set HANDSHAKE_F_REQ_COMPLETED but hp_done() may not have
finished, yet svc_sock_free() proceeds to kfree(svsk). The
cancel-loser fall-through inside svc_tcp_handshake() itself produces
the same window: when wait_for_completion_interruptible_timeout()
returns <= 0 (timeout or signal) and tls_handshake_cancel() returns
false, the function does not drain, returns, and svc_handle_xprt()
calls svc_xprt_received(), which clears XPT_BUSY and can drop the
last reference. A concurrent close then runs svc_sock_free() while
svc_tcp_handshake_done() is still updating xpt_flags and walking
svsk->sk_handshake_done.
The corruption surfaces as set_bit/clear_bit RMW into the freed
xpt_flags slab slot and as complete_all() walking and writing the
freed wait_queue_head_t list embedded in sk_handshake_done -- a
slab-corruption primitive, not a benign read. The path is reachable
on any TLS-enabled NFS server whenever a connection close overlaps
the tlshd downcall delivery window; the interruptible wait means
signal delivery suffices, not just SVC_HANDSHAKE_TO expiry.
Take svc_xprt_get(xprt) immediately before tls_server_hello_x509()
so the in-flight callback owns its own reference. Release it on the
two edges where the callback is guaranteed not to fire -- submission
failure from tls_server_hello_x509() and a successful
tls_handshake_cancel() -- and at the tail of
svc_tcp_handshake_done() after complete_all().
