https://notcve.org/view.php?id=CVE-2021-47020
In the Linux kernel, the following vulnerability has been resolved: soundwire: stream: fix memory leak in stream config error path When stream config is failed, master runtime will release all slave runtime in the slave_rt_list, but slave runtime is not added to the list at this time. This patch frees slave runtime in the config error path to fix the memory leak. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soundwire: stream: corrige la pérdida de memoria en la ruta de error de configuración de stream Cuando falla la configuración de stream, el tiempo de ejecución maestro liberará todo el tiempo de ejecución esclavo en Slave_rt_list, pero el tiempo de ejecución esclavo no se agrega a la lista. en este momento. Este parche libera el tiempo de ejecución esclavo en la ruta del error de configuración para corregir la pérdida de memoria. • https://git.kernel.org/stable/c/89e590535f32d4bc548bcf266f3b046e50942f6d https://git.kernel.org/stable/c/342260fe821047c3d515e3d28085d73fbdce3e80 https://git.kernel.org/stable/c/870533403ffa28ff63e173045fc5369365642002 https://git.kernel.org/stable/c/7c468deae306d0cbbd539408c26cfec04c66159a https://git.kernel.org/stable/c/2f17ac005b320c85d686088cfd4c2e7017912b88 https://git.kernel.org/stable/c/effd2bd62b416f6629e18e3ce077c60de14cfdea https://git.kernel.org/stable/c/48f17f96a81763c7c8bf5500460a359b9939359f •

In the Linux kernel, the following vulnerability has been resolved: m68k: mvme147,mvme16x: Don't wipe PCC timer config bits Don't clear the timer 1 configuration bits when clearing the interrupt flag and counter overflow. As Michael reported, "This results in no timer interrupts being delivered after the first. Initialization then hangs in calibrate_delay as the jiffies counter is not updated." On mvme16x, enable the timer after requesting the irq, consistent with mvme147.
