CVE-2021-47052 – crypto: sa2ul - Fix memory leak of rxd
https://notcve.org/view.php?id=CVE-2021-47052
In the Linux kernel, the following vulnerability has been resolved: crypto: sa2ul - Fix memory leak of rxd There are two error return paths that are not freeing rxd and causing memory leaks. Fix these. Addresses-Coverity: ("Resource leak") En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: sa2ul - Reparar la pérdida de memoria de rxd Hay dos rutas de retorno de error que no liberan rxd y causan pérdidas de memoria.

CVE-2021-47051 – spi: fsl-lpspi: Fix PM reference leak in lpspi_prepare_xfer_hardware()
https://notcve.org/view.php?id=CVE-2021-47051
In the Linux kernel, the following vulnerability has been resolved: spi: fsl-lpspi: Fix PM reference leak in lpspi_prepare_xfer_hardware() pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: spi: fsl-lpspi: corrige la fuga de referencia de PM en lpspi_prepare_xfer_hardware() pm_runtime_get_sync incrementará el contador de uso de PM incluso si falla. Olvidarse de poner en funcionamiento resultará en una fuga de referencia aquí. Solucionelo reemplazándolo con pm_runtime_resume_and_get para mantener el contador de uso equilibrado. • https://git.kernel.org/stable/c/944c01a889d97dc08e1b71f4ed868f4023fd6034 https://git.kernel.org/stable/c/4a01ad002d2e03c399af536562693752af7c81b1 https://git.kernel.org/stable/c/ce02e58ddf8658a4c3bed2296f32a5873b3f7cce https://git.kernel.org/stable/c/b8207bfc539cd07d15e753ff2d179c5b61c673b1 https://git.kernel.org/stable/c/6a2b5cee0d31ab6cc51030c441135b0e31217282 https://git.kernel.org/stable/c/a03675497970a93fcf25d81d9d92a59c2d7377a7 •
CVE-2021-47050 – memory: renesas-rpc-if: fix possible NULL pointer dereference of resource
https://notcve.org/view.php?id=CVE-2021-47050
In the Linux kernel, the following vulnerability has been resolved: memory: renesas-rpc-if: fix possible NULL pointer dereference of resource The platform_get_resource_byname() can return NULL which would be immediately dereferenced by resource_size(). Instead dereference it after validating the resource.

CVE-2021-47049 – Drivers: hv: vmbus: Use after free in __vmbus_open()
https://notcve.org/view.php?id=CVE-2021-47049
In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Use after free in __vmbus_open() The "open_info" variable is added to the &vmbus_connection.chn_msg_list, but the error handling frees "open_info" without removing it from the list. This will result in a use after free. First remove it from the list, and then free it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Controladores: hv: vmbus: Usar después de liberar en __vmbus_open() La variable "open_info" se agrega a &vmbus_connection.chn_msg_list, pero el manejo de errores libera "open_info" sin eliminarlo de la lista.
