13 Sep 2022 — 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 • CWE-125: Out-of-bounds Read •

05 Sep 2022 — An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. NOTE: the original discoverer disputes that the overflow can actually happen.
