Security readout for executives and security teams
Plain-English summary
CVE-2024-57983 is a Linux kernel memory corruption flaw in the th1520 mailbox driver. During system suspend or resume, the driver used an array too small for four interrupt-mask registers, which could corrupt memory. The CVSS rating is high because local, low-privileged access could affect confidentiality, integrity, and availability.
Executive priority
Treat as high priority for affected Linux platforms, but not internet-facing by itself. The main business risk is local privilege-adjacent kernel memory corruption on systems using this specific driver path. Prioritize confirmation and patching over emergency-wide response.
Technical view
The flaw is CWE-787 out-of-bounds write in Linux kernel mailbox: th1520. th1520_mbox_suspend_noirq and th1520_mbox_resume_noirq save and restore four MBOX ICU0 interrupt mask registers, but the storage array was incorrectly sized. The referenced stable commits correct the array size.
Likely exposure
Exposure appears limited to Linux kernels including and using the th1520 mailbox driver, especially affected 6.13-era kernel builds identified in the source bundle. Organizations should confirm whether vendor kernels include this driver and whether the referenced stable fixes are present.
Exploitation context
The source bundle lists CVSS AV:L/PR:L/UI:N, meaning exploitation requires local access and some privileges, without user interaction. CISA KEV status is false in the bundle, and no provided source states active exploitation.
Researcher notes
Evidence is narrow and kernel-specific. The affected surface is tied to suspend/resume paths in the th1520 mailbox driver. The bundle does not provide exploit details, real-world exploitation, or downstream distribution status, so validation should focus on driver presence and patch provenance.
Mitigation direction
- Apply vendor kernel updates that include the referenced stable fixes.
- Prioritize affected systems where local users or workloads are not fully trusted.
- Check embedded or custom kernel builds for the th1520 mailbox driver.
- Use vendor advisories rather than assuming mainline version labels match downstream kernels.
Validation and detection
- Inventory Linux kernel versions and downstream vendor patch levels.
- Check kernel source or package changelogs for the referenced fix commits.
- Confirm whether the th1520 mailbox driver is built or loaded.
- Review suspend and resume exposure on affected platforms.

Out-of-bounds Write
Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
