CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:HSummary
CVE-2024-0741 is a medium-severity Out-of-bounds Write (CWE-787) vulnerability in Mozilla Firefox. Its CVSS base score is 6.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 19% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-0741 is an out-of-bounds write vulnerability in the ANGLE graphics library that can corrupt memory and trigger a potentially exploitable crash. It affects Firefox versions prior to 122, Firefox ESR versions prior to 115.7, and Thunderbird versions prior to 115.7. The flaw carries a CVSS 3.1 score of 6.5 with network attack vector, low complexity, and high impact on availability.
An attacker can exploit the issue by serving specially crafted web content that triggers the out-of-bounds write when rendered in a vulnerable browser or email client. Successful exploitation requires user interaction such as visiting a malicious page or opening a malicious message, after which memory corruption may occur without further privileges.
Mozilla advisories MFSA2024-01 and MFSA2024-02, along with corresponding Debian LTS announcements, direct users to upgrade to the fixed releases Firefox 122, Firefox ESR 115.7, or Thunderbird 115.7. The referenced Mozilla bug report provides additional technical detail on the root cause and the applied correction.
The EPSS score has remained near 0.49 with no material rise from a low baseline after disclosure.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.
Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.
Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.
Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.
