mm: prevent poison consumption when splitting THP
When performing memory error injection on a THP (Transparent Huge Page)
mapped to userspace on an x86 server, the kernel panics with the following
trace. The expected behavior is to terminate the affected process instead
of panicking the kernel, as the x86 Machine Check code can recover from an
in-userspace #MC.
mce: [Hardware Error]: CPU 0: Machine Check Exception: f Bank 3: bd80000000070134
mce: [Hardware Error]: RIP 10:<ffffffff8372f8bc> {memchr_inv+0x4c/0xf0}

mce: [Hardware Error]: Machine check: Data load in unrecoverable area of kernel
Kernel panic - not syncing: Fatal local machine check
The root cause of this panic is that handling a memory failure triggered
by an in-userspace #MC necessitates splitting the THP. The splitting
process employs a mechanism, implemented in
try_to_map_unused_to_zeropage(), which reads the pages in the THP to
identify zero-filled pages. However, reading the pages in the THP results
in a second in-kernel #MC, occurring before the initial memory_failure()
completes, ultimately leading to a kernel panic. See the kernel panic
call trace on the two #MCs.
First Machine Check occurs // [1]
memory_failure() // [2]
try_to_split_thp_page()
split_huge_page()
split_huge_page_to_list_to_order()
__folio_split() // [3]
remap_page()
remove_migration_ptes()
remove_migration_pte()
try_to_map_unused_to_zeropage() // [4]
memchr_inv() // [5]
Second Machine Check occurs // [6]
Kernel panic
[1] Triggered by accessing a hardware-poisoned THP in userspace, which is
typically recoverable by terminating the affected process.
[2] Call folio_set_has_hwpoisoned() before try_to_split_thp_page().
[3] Pass the RMP_USE_SHARED_ZEROPAGE remap flag to remap_page().
[4] Try to map the unused THP to zeropage.
[5] Re-access pages in the hw-poisoned THP in the kernel.
[6] Triggered in-kernel, leading to a panic kernel.
In Step[2], memory_failure() sets the poisoned flag on the page in the THP
by TestSetPageHWPoison() before calling try_to_split_thp_page().
As suggested by David Hildenbrand, fix this panic by not accessing to the
poisoned page in the THP during zeropage identification, while continuing
to scan unaffected pages in the THP for possible zeropage mapping. This
prevents a second in-kernel #MC that would cause kernel panic in Step[4].
Thanks to Andrew Zaborowski for his initial work on fixing this issue. |
| The com.glitter.caller.screen (aka iCaller, Caller Theme & Dialer) application through 1.1 for Android enables any application (with no permissions) to place phone calls without user interaction by sending a crafted intent via the com.glitter.caller.screen.DialerActivity component. |
| A stack-based buffer overflow vulnerability exists in ActFax Server version 4.32, specifically in the "Import Users from File" functionality of the client interface. The application fails to properly validate the length of tab-delimited fields in .exp files, leading to unsafe usage of strcpy() during CSV parsing. An attacker can exploit this vulnerability by crafting a malicious .exp file and importing it using the default character set "ECMA-94 / Latin 1 (ISO 8859)". Successful exploitation may result in arbitrary code execution, leading to full system compromise. User interaction is required to trigger the vulnerability. |
| Ambiguous wording in the web interface of the ctrlX OS setup mechanism could lead the user to believe that the backup file is encrypted when a password is set. However, only the private key - if available in the backup - is encrypted, while the backup file itself remains unencrypted. |
| RestDB's Codehooks.io MCP Server is an MCP server on the Codehooks.io platform. Prior to version 0.2.2, the MCP server is written in a way that is vulnerable to command injection attacks as part of some of its MCP Server tools definition and implementation. This could result in a user initiated remote command injection attack on a running MCP Server. This issue has been patched in version 0.2.2. |
| The W3 Total Cache WordPress plugin before 2.8.13 is vulnerable to command injection via the _parse_dynamic_mfunc function, allowing unauthenticated users to execute PHP commands by submitting a comment with a malicious payload to a post. |
| The E-Mail Security Virtual Appliance (ESVA) (tested on version ESVA_2057) contains an unauthenticated command injection vulnerability in the learn-msg.cgi script. The CGI handler fails to sanitize user-supplied input passed via the id parameter, allowing attackers to inject arbitrary shell commands. Exploitation requires no authentication and results in full command execution on the underlying system. |
| Cyclope Employee Surveillance Solution versions 6.x is vulnerable to a SQL injection flaw in its login mechanism. The username parameter in the auth-login POST request is not properly sanitized, allowing attackers to inject arbitrary SQL statements. This can be leveraged to write and execute a malicious PHP file on disk, resulting in remote code execution under the SYSTEM user context. |
| fblog through 983bede allows account takeover via the password reset feature because SERVER_NAME is not configured and thus a reset depends on the Host HTTP header. |
| CuteFlow version 2.11.2 and earlier contains an arbitrary file upload vulnerability in the restart_circulation_values_write.php script. The application fails to validate or restrict uploaded file types, allowing unauthenticated attackers to upload arbitrary PHP files to the upload/___1/ directory. These files are then accessible via the web server, enabling remote code execution. |
| Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in masterbip MasterBip para Elementor masterbip-for-elementor allows DOM-Based XSS.This issue affects MasterBip para Elementor: from n/a through <= 1.6.3. |
| In the Linux kernel, the following vulnerability has been resolved:
dccp: Fix out of bounds access in DCCP error handler
There was a previous attempt to fix an out-of-bounds access in the DCCP
error handlers, but that fix assumed that the error handlers only want
to access the first 8 bytes of the DCCP header. Actually, they also look
at the DCCP sequence number, which is stored beyond 8 bytes, so an
explicit pskb_may_pull() is required. |
| The UrbanGo Membership plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.0.4. This is due to the plugin allowing users who are registering new accounts to set their own role or by supplying 'user_register_role' field. This makes it possible for unauthenticated attackers to gain elevated privileges by creating an account with the administrator role. |
| Deserialization of Untrusted Data vulnerability in add-ons.org PDF for Gravity Forms + Drag And Drop Template Builder pdf-for-gravity-forms allows Object Injection.This issue affects PDF for Gravity Forms + Drag And Drop Template Builder: from n/a through <= 6.5.0. |
| Simple Web Server 2.2 rc2 contains a stack-based buffer overflow vulnerability in its handling of the Connection HTTP header. When a remote attacker sends an overly long string in this header, the server uses vsprintf() without proper bounds checking, leading to a buffer overflow on the stack. This flaw allows remote attackers to execute arbitrary code with the privileges of the web server process. The vulnerability is triggered before authentication. |
| The Admission AppManager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'q' parameter in versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. |
| PHP Volunteer Management System v1.0.2 contains an arbitrary file upload vulnerability in its document upload functionality. Authenticated users can upload files to the mods/documents/uploads/ directory without any restriction on file type or extension. Because this directory is publicly accessible and lacks execution controls, attackers can upload a malicious PHP payload and execute it remotely. The application ships with default credentials, making exploitation trivial. Once authenticated, the attacker can upload a PHP shell and trigger it via a direct GET request. |
| The Add custom page template plugin for WordPress is vulnerable to PHP Code Injection leading to Remote Code Execution in all versions up to, and including, 2.0.1 via the 'acpt_validate_setting' function. This is due to insufficient sanitization of the 'template_name' parameter. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server. |
| Lattice Semiconductor ispVM System v18.0.2 contains a buffer overflow vulnerability in its handling of .xcf project files. When parsing the version attribute of the ispXCF XML tag, the application fails to properly validate input length, allowing a specially crafted file to overwrite memory on the stack. This can result in arbitrary code execution under the context of the user who opens the file. The vulnerability is triggered locally by opening a malicious .xcf file and does not require elevated privileges. |
| A DLL hijacking vulnerability in iTop VPN v16.0 allows attackers to execute arbitrary code via placing a crafted DLL file into the path \ProgramData\iTop VPN\Downloader\vpn6. |
