| In the Linux kernel, the following vulnerability has been resolved:
io-wq: check that the predecessor is hashed in io_wq_remove_pending()
io_wq_remove_pending() needs to fix up wq->hash_tail[] if the cancelled
work was the tail of its hash bucket. When doing this, it checks whether
the preceding entry in acct->work_list has the same hash value, but
never checks that the predecessor is hashed at all. io_get_work_hash()
is simply atomic_read(&work->flags) >> IO_WQ_HASH_SHIFT, and the hash
bits are never set for non-hashed work, so it returns 0. Thus, when a
hashed bucket-0 work is cancelled while a non-hashed work is its list
predecessor, the check spuriously passes and a pointer to the non-hashed
io_kiocb is stored in wq->hash_tail[0].
Because non-hashed work is dequeued via the fast path in
io_get_next_work(), which never touches hash_tail[], the stale pointer
is never cleared. Therefore, after the non-hashed io_kiocb completes and
is freed back to req_cachep, wq->hash_tail[0] is a dangling pointer. The
io_wq is per-task (tctx->io_wq) and survives ring open/close, so the
dangling pointer persists for the lifetime of the task; the next hashed
bucket-0 enqueue dereferences it in io_wq_insert_work() and
wq_list_add_after() writes through freed memory.
Add the missing io_wq_is_hashed() check so a non-hashed predecessor
never inherits a hash_tail[] slot. |
| A vulnerability was identified in imvks786 student_management_system up to 9599b560ad3c3b83e75d328b76bedcd489ef1f46. This affects an unknown function of the file /index.ph of the component Login. Such manipulation of the argument usr/pwd leads to sql injection. The attack can be executed remotely. The exploit is publicly available and might be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet. |
| A DLL search order hijacking vulnerability in Thermalright TR-VISION HOME on Windows (64-bit) allows a local attacker to escalate privileges via DLL side-loading. The application loads certain dynamic-link library (DLL) dependencies using the default Windows search order, which includes directories that may be writable by non-privileged users.\n\n\n\nBecause these directories can be modified by unprivileged users, an attacker can place a malicious DLL with the same name as a legitimate dependency in a directory that is searched before trusted system locations. When the application is executed, which is always with administrative privileges, the malicious DLL is loaded instead of the legitimate library.\n\n\n\nThe application does not enforce restrictions on DLL loading locations and does not verify the integrity or digital signature of loaded libraries. As a result, attacker-controlled code may be executed within the security context of the application, allowing arbitrary code execution with elevated privileges.\n\n\n\nSuccessful exploitation requires that an attacker place a crafted malicious DLL in a user-writable directory that is included in the application's DLL search path and then cause the affected application to be executed. Once loaded, the malicious DLL runs with the same privileges as the application.\n\n\n\nThis issue affects \nTR-VISION HOME versions up to and including 2.0.5. |
| A vulnerability was found in code-projects Vehicle Management System 1.0. This impacts an unknown function of the file newdriver.php of the component New Driver Registration Form. Performing a manipulation of the argument photo results in unrestricted upload. The attack may be initiated remotely. The exploit has been made public and could be used. |
| The bac-scanresult method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input. |
| The ugw-delete-file method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input. |
| The ugw-logstop method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input. |
| The ugw-restore method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input. |
| The ugw-restoreinfo method allows a remote attacker with user privileges to delete arbitrary local files due to insufficient validation of user-controlled input. |
| The ugw-logstop method allows a remote attacker with user privileges to terminate arbitrary processes due to insufficient validation of user-supplied input. |
| The ugw-logread method allows a remote attacker with user privileges to access arbitrary local files due to insufficient validation of user-supplied input. |
| A remote attacker with user privileges can exploit a stack buffer overflow to gain full system access as root. |
| A remote attacker with user privileges can exploit a stack buffer overflow in dali-devconfig to gain full system access as root. |
| Bludit is a content management system. Versions prior to 3.22.0 have a vulnerability in the user management logic that allows deactivated accounts to maintain access via persistent authentication tokens. When an administrator disables a user account, the application fails to invalidate or clear the associated tokenAuth and tokenRemember fields in the JSON database. Consequently, any user with a pre-existing "Remember Me" cookie can bypass the account disablement and maintain a valid authenticated state. Version 3.22.0 patches the issue. |
| A remote attacker with user privileges can exploit a stack buffer overflow in gdv-serverconfig to gain full system access as root. |
| Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 16 file-manager endpoints in Termix prior to version 2.3.2 do not verify that the requesting user owns the SSH session identified by `sessionId`. An authenticated attacker who knows or guesses another user's active `sessionId` can read, write, delete, download, and execute files on the victim's connected SSH host. Version 2.3.2 patches the issue. |
| A flaw has been found in Tenda W20E 15.11.0.6. This issue affects the function formPortalAuth of the file /goform/PortalAuth of the component Web Management Interface. Executing a manipulation of the argument gotoUrl can lead to stack-based buffer overflow. The attack can be launched remotely. The exploit has been published and may be used. |
| A flaw has been found in GL.iNet GL-MT3000 4.4.5. This impacts the function snprintf of the file /cgi-bin/glc of the component FTP Protocol Handler. Executing a manipulation of the argument media_dir can lead to command injection. It is possible to launch the attack remotely. Upgrading to version 4.8.1 will fix this issue. You should upgrade the affected component. The vendor explains: "In version 4.8.1, before writing media_dir to the FTP configuration command, the code escapes single quotes using escape_single_quote(). The payloads in the report—which rely on closing a single quote, appending commands with a semicolon, and commenting out the tail with #—cannot escape execution under the current code path. We also verified this on a GL‑MT3000 device running firmware version 4.8.1 using similar payloads calling the /NAS_API_SET_PROTO_CONFIG interface. Although the interface returned success, the marker file intended to prove command execution was not created; the payload was written into /etc/vsftpd.conf only as ordinary configuration content and did not trigger any shell command execution. Therefore, with the current firmware version and default runtime environment, we could not reproduce the claimed “unauthorized command injection in set_proto_config”." |
| MoviePilot contains a path traversal vulnerability in the AliPan, U115, and Rclone cloud storage download handlers where the local destination path is constructed by concatenating the configured download directory with a filename taken directly from remote cloud API metadata without basename normalization or path validation. An attacker who controls a filename returned by a remote cloud storage API can include traversal sequences ../ in the filename to cause downloaded content to be written outside the configured download directory, potentially overwriting arbitrary files including configuration or plugin files reachable by the application process. |
| Heap buffer overflow in TabStrip in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium) |
