CVE-2024-57990: wifi: mt76: mt7925: fix off by one in mt7925_load_clc()
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7925: fix off by one in mt7925_load_clc()
This comparison should be >= instead of > to prevent an out of bounds
read and write.
Security readout for executives and security teams
Plain-English summary
CVE-2024-57990 is a Linux kernel Wi-Fi driver bug affecting the mt76 mt7925 code path. A local user could potentially trigger memory corruption, with high confidentiality, integrity, and availability impact. The public record does not show active exploitation, but affected Linux systems with MediaTek MT7925 Wi-Fi should be prioritized for kernel updates.
Executive priority
Treat this as a high-priority patching item for Linux fleets with MT7925 Wi-Fi exposure. It is less urgent for servers or images without that driver path. Because exploitation is local and not publicly confirmed in the provided sources, prioritize based on hardware exposure and endpoint risk.
Technical view
The issue is an off-by-one comparison in mt7925_load_clc(), where a boundary check used > instead of >=. The Linux kernel fix states this could cause an out-of-bounds read and write. CVSS 3.1 is 7.8 with local, low-complexity, low-privilege exploitation assumptions and high CIA impact.
Likely exposure
Exposure is most likely on Linux systems running affected kernel versions with the mt76 mt7925 MediaTek Wi-Fi driver path present or enabled. Systems without that hardware, driver, or affected kernel lineage are less likely exposed. The source bundle does not provide CPEs or distribution-specific package mappings.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source states active exploitation. The CVSS vector indicates local access with low privileges and no user interaction. Public evidence supports a serious memory-safety flaw, not confirmed real-world exploitation.
Researcher notes
The source evidence is concise: a Linux kernel stable fix for CWE-193 in mt7925_load_clc(). The affected-version data is limited and includes no CPEs, exploit details, or distribution status. Validation should rely on kernel build provenance, downstream advisories, and whether the referenced stable commits are included.
Mitigation direction
Inventory Linux systems for affected kernels and MediaTek MT7925 Wi-Fi driver usage.
Apply distribution kernel updates that include the referenced Linux stable fixes.
Prioritize laptops, workstations, and appliances using MT7925 Wi-Fi hardware.
If updates are unavailable, check vendor guidance for temporary mitigations.
Disable unused MT7925 Wi-Fi capability where operationally acceptable and vendor-supported.
Validation and detection
Confirm the running kernel version against vendor advisories and the CVE record.
Check whether the mt76 mt7925 driver is present, loaded, or required.
Verify installed kernel packages include one of the referenced stable fixes.
Confirm patched systems rebooted into the updated kernel.
Track exceptions for systems lacking vendor-provided fixed packages.
