An out-of-bounds access issue was found in the Linux kernel sound subsystem. It could occur when the 'id->name' provided by the user did not end with '\0'. A privileged local user could pass a specially crafted name through ioctl() interface and crash the system or potentially escalate their privileges on the system. Se ha encontrado un problema de acceso fuera de límites en el subsistema de sonido del kernel de Linux. Podía ocurrir cuando el "id-)name proporcionado por el usuario no terminaba con "\0". • https://github.com/torvalds/linux/commit/5934d9a0383619c14df91af8fd76261dc3de2f5f https://github.com/torvalds/linux/commit/6ab55ec0a938c7f943a4edba3d6514f775983887 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2022-3077
A buffer overflow vulnerability was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way it handled the I2C_SMBUS_BLOCK_PROC_CALL case (via the ioctl I2C_SMBUS) with malicious input data. This flaw could allow a local user to crash the system. Se encontró una vulnerabilidad de desbordamiento de búfer en el controlador de host iSMT SMBus del kernel de Linux en la forma en que manejaba el caso I2C_SMBUS_BLOCK_PROC_CALL (por el ioctl I2C_SMBUS) con datos de entrada maliciosos. Este fallo podría permitir a un usuario local bloquear el sistema A buffer overflow vulnerability was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way it handled the I2C_SMBUS_BLOCK_PROC_CALL case (via the ioctl I2C_SMBUS) with malicious input data. In particular, the userspace controllable "data->block[0]" variable was not capped to a number between 0-255 and then used as the size of a memcpy, thus possibly writing beyond the end of dma_buffer. • https://github.com/torvalds/linux/commit/690b2549b19563ec5ad53e5c82f6a944d910086e https://access.redhat.com/security/cve/CVE-2022-3077 https://bugzilla.redhat.com/show_bug.cgi?id=2123309 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
