In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: fix potential memory leakage when reading chip temperature
Without this commit, reading chip temperature will cause memory leakage.
Security readout for executives and security teams
Plain-English summary
CVE-2024-38563 is a Linux kernel issue in the MediaTek mt7996 Wi-Fi driver. Reading the chip temperature can leak memory. The business risk is most relevant to systems using this driver and hardware, where repeated legitimate monitoring could degrade stability over time.
Executive priority
Treat as a targeted kernel stability issue. Patch during normal maintenance unless affected Wi-Fi hardware is widely deployed in critical systems, where it should move sooner to reduce outage risk.
Technical view
The Linux kernel mt76 mt7996 driver had a memory leak in the chip temperature read path. The source bundle identifies stable kernel fixes and affected Linux kernel entries, but provides no CVSS, CWE, or detailed attack prerequisites.
Likely exposure
Exposure is likely limited to Linux systems with the mt76 mt7996 Wi-Fi driver and affected kernel versions listed in the CVE data. Systems without this driver or hardware are unlikely to be affected based on the provided sources.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed as KEV. The known trigger is reading chip temperature, which suggests stability and resource-exhaustion risk rather than confirmed remote compromise.
Researcher notes
Evidence is sparse: no CVSS, CWE, exploit report, or detailed affected-version ranges beyond the CVE bundle. The strongest technical signal is the upstream stable fix description tying chip temperature reads to memory leakage.
Mitigation direction
Update to a kernel or distro package containing the referenced stable fixes.
Check Linux distribution advisories for the exact fixed package version.
Prioritize systems using MediaTek mt7996 Wi-Fi hardware or mt76 mt7996 driver.
Track remediation through normal kernel patch management workflows.
Validation and detection
Inventory Linux systems for affected kernel versions from the CVE record.
Confirm whether mt76 mt7996 driver or matching hardware is present.
Verify installed kernel includes one of the referenced stable fixes.
Review monitoring workflows that read Wi-Fi chip temperature frequently.
