Common Weakness Enumeration
CWE-843
AllowedAccess of Resource Using Incompatible Type ('Type Confusion')
Abstraction: Base · Status: Incomplete
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
1041 vulnerabilities reference this CWE, most recent first.
GHSA-9R58-49JG-HRQ7
Vulnerability from github – Published: 2022-05-24 16:44 – Updated: 2025-11-25 18:32
VLAI
Details
The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.

GHSA-9V26-H3PH-P8V7
Vulnerability from github – Published: 2022-07-05 00:00 – Updated: 2022-07-14 00:00
VLAI
Details
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.

Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.3.1.21155. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the w method of XFA Layout objects. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5020.
