CVE-2026-58718
MediumCVSS 6.7Summary
In smmu_detach_dev_nested of arm-smmu-v3.c, there is a possible escalation of privilege due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
Risk Assessment
An attacker with System privileges could gain higher privileges, potentially leading to full system control. The risk is severe as high privileges are already required.
Recommendation
It is recommended to urgently apply security patches from the vendor. Also monitor system logs for unusual activity.
