CVE-2025-38094 - Cirrus Logic Macb Deadlock Vulnerability
CVE ID : CVE-2025-38094
Published : July 3, 2025, 8:15 a.m. | 54 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved: net: cadence: macb: Fix a possible deadlock in macb_halt_tx. There is a situation where after THALT is set high, TGO stays high as well. Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock. That deadlock was noticed on a sama5d4 device that stayed locked for days. Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.
Severity: 0.0 | NA
