| In the Linux kernel, the following vulnerability has been resolved:
arm64: io: Extract user memory type in ioremap_prot()
The only caller of ioremap_prot() outside of the generic ioremap()
implementation is generic_access_phys(), which passes a 'pgprot_t' value
determined from the user mapping of the target 'pfn' being accessed by
the kernel. On arm64, the 'pgprot_t' contains all of the non-address
bits from the pte, including the permission controls, and so we end up
returning a new user mapping from ioremap_prot() which faults when
accessed from the kernel on systems with PAN:
| Unable to handle kernel read from unreadable memory at virtual address ffff80008ea89000
| ...
| Call trace:
| __memcpy_fromio+0x80/0xf8
| generic_access_phys+0x20c/0x2b8
| __access_remote_vm+0x46c/0x5b8
| access_remote_vm+0x18/0x30

| vfs_read+0xe4/0x2b0
| ksys_read+0xcc/0x178
| __arm64_sys_read+0x4c/0x68
Extract only the memory type from the user 'pgprot_t' in ioremap_prot()
and assert that we're being passed a user mapping, to protect us against
any changes in future that may require additional handling. To avoid
falsely flagging users of ioremap(), provide our own ioremap() macro
which simply wraps __ioremap_prot(). |
| In AzeoTech DAQFactory versions 21.1 and prior, a Type Confusion vulnerability can be exploited by an attacker using specially crafted .ctl files which can result in code execution. |
| Memory safety bug fixed in Firefox 152. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Thunderbird 152, and Thunderbird 140.12. |
| LibreOffice Calc can import tracked changes from a spreadsheet document. A heap buffer overflow existed when a document reused the same change identifier for two different kinds of change. The importer then treated one change object as a different, larger type and wrote past the end of its allocation. In fixed versions records with a duplicate identifier are rejected. |
| JIT miscompilation in the DOM: Core & HTML component. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Firefox ESR 115.37, Thunderbird 152, and Thunderbird 140.12. |
| In ParsePayloads of AudioSdpParser.cpp, there is a possible memory corruption due to type confusion. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. |
| A type confusion issue was addressed with improved checks. This issue is fixed in iOS 18.3 and iPadOS 18.3, macOS Sequoia 15.3, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.3, visionOS 2.3. An attacker on the local network may cause an unexpected app termination. |
| LibreOffice can import documents in the OOXML format (DOCX). A heap buffer overflow existed when replaying deferred parser events for a text box element. A handler object was assumed to be of one type and written to at that type's field layout, but it could be a smaller object, so the write landed past the end of the allocation. In fixed versions the type is checked before the write. |
| Access of resource using incompatible type ('type confusion') in Windows Kernel-Mode Drivers allows an authorized attacker to elevate privileges locally. |
| vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, by combining Buffer.call.call({}.__lookupGetter__, Buffer, "__proto__"), Buffer.call.call({}.__lookupSetter__, Buffer, "__proto__"), and Node.js's ERR_INVALID_ARG_TYPE Error, the host's TypeError constructor can be obtained, which allows the escape from the sandbox. This allows attackers to run arbitrary code. This issue has been patched in version 3.11.4. |
| Race in V8 in Google Chrome prior to 144.0.7559.99 allowed a remote attacker to potentially exploit type confusion via a crafted HTML page. (Chromium security severity: High) |
| A flaw was found in 389 Directory Server. A type confusion in the SSO token extended operation handler causes partial stack address information to be disclosed in LDAP responses to authenticated users. |
| Access of resource using incompatible type ('type confusion') in Microsoft Office allows an unauthorized attacker to execute code locally. |
| Inappropriate implementation in V8 in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) |
| Type Confusion in XML in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted XML file. (Chromium security severity: Medium) |
| In the Linux kernel, the following vulnerability has been resolved:
AppArmor: Allow apparmor to handle unaligned dfa tables
The dfa tables can originate from kernel or userspace and 8-byte alignment
isn't always guaranteed and as such may trigger unaligned memory accesses
on various architectures. Resulting in the following

| Windows Remote Desktop Services Remote Code Execution Vulnerability |
| The Helpfulcrowd Product Reviews plugin for WordPress is vulnerable to Authorization Bypass via PHP Type Juggling in versions up to, and including, 1.2.9. This is due to the `helpfulcrowd_validate_token()` function using a loose comparison operator (`!=`) instead of a strict comparison (`!==`) when validating the `token` parameter, while the corresponding REST route `/wp-json/helpfulcrowd/v1/update-settings` is registered with a `permission_callback` of `__return_true`, making it reachable by unauthenticated users; submitting a JSON boolean `true` as the `token` value causes PHP's loose comparison to evaluate as equal to the non-empty base64-encoded secret string, bypassing the check entirely. This makes it possible for unauthenticated attackers to invoke `helpfulcrowd_settings_endpoint()` and write arbitrary attacker-controlled key-value pairs directly into the `helpfulcrowd_options` WordPress database option via `update_option()` without any sanitization or allowlist filtering, enabling full unauthenticated modification of the plugin's stored configuration. |
| Type Confusion in Bindings in Google Chrome prior to 149.0.7827.103 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) |
| A vulnerability was determined in USCiLab Cereal up to 1.3.2. Affected is an unknown function of the component Shared Pointer Handler. Executing a manipulation can lead to type confusion. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure. |
