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...

CVE-2022-49613

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-2022-49486

CVE-2022-49486 relates to the Linux kernel ASoC driver for i.MX SGTL5000. The vulnerability is a refcount leak in imx_sgtl5000_probe caused by improper handling of a reference taken by of_find_i2c_device_by_node(); in error paths the driver should call put_device() to drop the reference. A resolv...

CVE-2022-49462

The CVE-2022-49462 issue affects the Linux kernel DRM MSM A6xx driver (a6xx_gpu_init). Root cause: of_parse_phandle() returns a node pointer with refcount incremented and a missing of_node_put() leads to a refcount leak. The code path in a6xx_gmu_init() passes the node to of_find_device_by_node()...
