CVE-2026-20477
MediumCVSS 6.0Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
In the display component, a missing bounds check could lead to an out-of-bounds write, allowing local escalation of privilege if the attacker already has System privilege. No user interaction is needed.
Risk Assessment
An attacker with System privileges could gain even higher privileges, increasing the risk of full device control.
Recommendation
Apply patch ALPS11009963 which adds bounds checking.
