CVE-2024-23222
Description
A flaw was found in WebKitGTK. Processing malicious web content may lead to remote code execution due to a type confusion issue. This vulnerability is known to be actively exploited in the wild and was included in the CISA's KEV catalog.
Statement
This flaw depends on the WebKitGTK JIT engine to be enabled. This feature has been disabled in Red Hat Enterprise Linux 8.8 and 9.2 by the errata RHSA-2023:4202 and RHSA-2023:4201. Therefore, Red Hat Enterprise Linux 8.8 and 9.2, when these errata are applied, and newer versions are not affected by this vulnerability.

To exploit this flaw, an attacker needs to trick a user into processing or loading malicious web content. For this reason, this flaw was rated with an important, and not critical, severity.
Mitigation
Do not process or load untrusted web content. Please update the affected package as soon as possible.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability,Integrity,Confidentiality
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart
When a memory buffer is accessed using the wrong type, it could read or write memory out of the bounds of the buffer, if the allocated buffer is smaller than the type that the code is attempting to access, leading to a crash and possibly code execution.
