CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: fix UAF in hci_le_create_cis_sync
hci_le_create_cis_sync() dereferences conn->conn_timeout after releasing
both rcu_read_lock() and hci_dev_lock(hdev). The conn pointer was
obtained from an RCU-protected iteration over hdev->conn_hash.list and
is not valid once these locks are dropped. A concurrent disconnect can
free the hci_conn between the unlock and the dereference, causing a
use-after-free read.
The cancellation mechanism in hci_conn_del() cannot prevent this because
hci_le_create_cis_pending() queues hci_create_cis_sync with data=NULL:
hci_cmd_sync_queue(hdev, hci_create_cis_sync, NULL, NULL);
While hci_conn_del() dequeues with data=conn:
hci_cmd_sync_dequeue(hdev, NULL, conn, NULL);
Since NULL != conn, the lookup in _hci_cmd_sync_lookup_entry() never
matches, and the pending work item is not cancelled.
Fix this by saving conn->conn_timeout into a local variable while the
locks are still held, so the stale conn pointer is never dereferenced
after unlock.
This is the same class of bug as the one fixed by commit 035c25007c9e
("Bluetooth: hci_sync: Fix UAF on le_read_features_complete") which
addressed the identical pattern in a different function.
This vulnerability was identified using 0sec.ai, an open-source
automated security auditing platform (https://github.com/0sec-labs). |
| Use after free in Windows Update Orchestrator Service allows an authorized attacker to elevate privileges locally. |
| A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory handling and result in memory corruption. |
| A weakness has been identified in libimobiledevice up to 1.4.0. This issue affects the function service_receive of the file src/afc.c of the component AFC Service. Executing a manipulation can lead to double free. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: HWS, Handle destroying table that has a miss table
If a table has a miss table that was created by
'mlx5hws_table_set_default_miss' API function, its miss_tbl
keeps the table that points to it in a list.
If such table is deleted, we need to also remove it from the
miss_tbl list, otherwise the node in miss_tbl list will contain
garbage. |
| A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). |
| A flaw was found in m17n-lib. A user providing specially crafted text input can trigger a heap use-after-free condition during input-method state transitions. Under specific conditions, the library frees an internal input context object but subsequently attempts to write to that freed memory. This issue can cause applications relying on the library to crash, leading to a Denial of Service (DoS), or potentially allow arbitrary code execution. |
| adm-zip through 0.6.1 contains a duplicate-entry validation bypass that allows attackers to evade the readEntries() check by using canonically equivalent entry names like './hello.txt' and 'hello.txt'. Attackers can craft ZIP archives where getEntry() or readAsText() validates benign content while extractAllTo() writes malicious content to the same path, bypassing integrity checks. |

| Use after free in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Device Association Service allows an authorized attacker to elevate privileges locally. |
| Use after free in WebDAV allows an authorized attacker to elevate privileges locally. |
