| In the Linux kernel, the following vulnerability has been resolved:
net: sock: fix hardened usercopy panic in sock_recv_errqueue
skbuff_fclone_cache was created without defining a usercopy region,
[1] unlike skbuff_head_cache which properly whitelists the cb[] field.
[2] This causes a usercopy BUG() when CONFIG_HARDENED_USERCOPY is
enabled and the kernel attempts to copy sk_buff.cb data to userspace
via sock_recv_errqueue() -> put_cmsg().
The crash occurs when: 1. TCP allocates an skb using alloc_skb_fclone()
(from skbuff_fclone_cache) [1]
2. The skb is cloned via skb_clone() using the pre-allocated fclone
[3] 3. The cloned skb is queued to sk_error_queue for timestamp
reporting 4. Userspace reads the error queue via recvmsg(MSG_ERRQUEUE)
5. sock_recv_errqueue() calls put_cmsg() to copy serr->ee from skb->cb
[4] 6. __check_heap_object() fails because skbuff_fclone_cache has no
usercopy whitelist [5]
When cloned skbs allocated from skbuff_fclone_cache are used in the
socket error queue, accessing the sock_exterr_skb structure in skb->cb
via put_cmsg() triggers a usercopy hardening violation:

The crash offset 296 corresponds to skb2->cb within skbuff_fclones:
- sizeof(struct sk_buff) = 232 - offsetof(struct sk_buff, cb) = 40 -
offset of skb2.cb in fclones = 232 + 40 = 272 - crash offset 296 =
272 + 24 (inside sock_exterr_skb.ee)
This patch uses a local stack variable as a bounce buffer to avoid the hardened usercopy check failure.

| An open debug interface was reported in the Legion Space software included on certain Legion devices that could allow a local attacker to execute arbitrary code. |
| There is a possible escalation of privilege due to test/debugging code left in a production build. This could lead to physical escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| An authenticated admin user with access to both the management WebUI and command line interface on a Firebox can enable a diagnostic debug shell by uploading a platform and version-specific diagnostic package and executing a leftover diagnostic command.
This issue affects Fireware OS: from 12.0 before 12.11.2. |
| The Four-Faith F3x36 router using firmware v2.0.0 is vulnerable to authentication bypass due to hard-coded credentials in the administrative web server. An attacker with knowledge of the credentials can gain administrative access via crafted HTTP requests. This issue appears similar to CVE-2023-32645. |

| The Four-Faith F3x36 router using firmware v2.0.0 is vulnerable to an
authentication bypass vulnerability in the administrative web server. Authentication is not enforced on some administrative functionality when using the "bapply.cgi" endpoint instead of the normal "apply.cgi" endpoint. A remote and unauthenticated can use this vulnerability to modify settings or chain with existing authenticated vulnerabilities. |
| There is a possible LCS signing enforcement missing due to test/debugging code left in a production build. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| A leftover debug code vulnerability exists in the cli_server debug functionality of Tp-Link ER7206 Omada Gigabit VPN Router 1.4.1 Build 20240117 Rel.57421. A specially crafted series of network requests can lead to arbitrary command execution. An attacker can send a sequence of requests to trigger this vulnerability. |
| Active debug code vulnerability exists in PLANEX COMMUNICATIONS wireless LAN routers. If a logged-in user who knows how to use the debug function accesses the device's management page, an unintended operation may be performed. Note that MZK-MF300N is no longer supported, therefore the update for this product is not provided. |

| Artifex Ghostscript before 10.03.1, when Tesseract is used for OCR, has a directory traversal issue that allows arbitrary file reading (and writing of error messages to arbitrary files) via OCRLanguage. For example, exploitation can use debug_file /tmp/out and user_patterns_file /etc/passwd. |
| The Synthetic Monitoring Agent for Grafana's Synthetic Monitoring application provides probe functionality and executes network checks for monitoring remote targets. Users running the Synthetic Monitoring agent prior to version 0.12.0 in their local network are impacted. The authentication token used to communicate with the Synthetic Monitoring API is exposed through a debugging endpoint. This token can be used to retrieve the Synthetic Monitoring checks created by the user and assigned to the agent identified with that token. The Synthetic Monitoring API will reject connections from already-connected agents, so access to the token does not guarantee access to the checks. Version 0.12.0 contains a fix. Users are advised to rotate the agent tokens. After upgrading to version v0.12.0 or later, it's recommended that users of distribution packages review the configuration stored in `/etc/synthetic-monitoring/synthetic-monitoring-agent.conf`, specifically the `API_TOKEN` variable which has been renamed to `SM_AGENT_API_TOKEN`. As a workaround for previous versions, it's recommended that users review the agent settings and set the HTTP listening address in a manner that limits the exposure, for example, localhost or a non-routed network, by using the command line parameter `-listen-address`, e.g. `-listen-address localhost:4050`. |

| A vulnerability was found in Netis WF-2404 1.1.124EN. It has been declared as critical. This vulnerability affects unknown code of the component UART. The manipulation leads to hardware allows activation of test or debug logic at runtime. It is possible to launch the attack on the physical device. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. |
| Active debug code in the B. Braun Melsungen AG SpaceCom Version L8/U61, and the Data module compactplus Versions A10 and A11 and earlier enables attackers in possession of cryptographic material to access the device as root. |
