CVE-2022-49613 serial: 8250: Fix PM usage_count for console handover

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. Therefore, it will not call pmruntimegetsync. Later, when the actual...

CVE-2022-49613

CVE-2022-49613 affects the Linux kernel serial driver 8250 console handover. When a console is enabled, univ8250_console_setup() runs before .dev is bound to the uart_port, so pm_runtime_get_sync() is skipped. Later, during handover, serial8250_console_exit() may call pm_runtime_put_sync() with a...

kernel: soundwire: bus: Fix unbalanced pm_runtime_put() causing usage count underflow

A reference count underflow flaw was found in the Linux kernel's SoundWire bus driver. When pmruntimeresumeandget returns an error -EACCES, the code continues execution and calls pmruntimeput at the end, even though the usage count was never incremented. This causes a usage count underflow in the...
