CVE-2026-99089

A flaw was found in the Linux kernel's Samsung I2S audio driver. The driver's initialization routine configures runtime power management without enabling the associated operating clock, leaving clock reference counters out of balance. When the device transitions into a suspended state, the kernel attempts to disable the clock more times than it was enabled. A local attacker could exploit this issue by triggering power management operations on the affected audio device, resulting in kernel warnings and a potential denial of service (DoS).
