Descriptions
In the Linux kernel, the following vulnerability has been resolved:
init/main.c: Fix potential static_command_line memory overflow
We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for
static_command_line, but the strings copied into static_command_line are
extra_command_line and command_line, rather than extra_command_line and
boot_command_line.
When strlen(command_line) > strlen(boot_command_line), static_command_line
will overflow.
This patch just recovers strlen(command_line) which was miss-consolidated
with strlen(boot_command_line) in the commit f5c7310ac73e ("init/main: add
checks for the return value of memblock_alloc*()")
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: init/main.c: soluciona un posible desbordamiento de memoria de static_command_line Asignamos memoria de tamaño 'xlen + strlen(boot_command_line) + 1' para static_command_line, pero las cadenas copiadas en static_command_line son extra_command_line y command_line, en lugar de extra_command_line y boot_command_line. Cuando strlen(command_line) > strlen(boot_command_line), static_command_line se desbordará. Este parche simplemente recupera strlen(command_line) que no se consolidó con strlen(boot_command_line) en el commit f5c7310ac73e ("init/main: agregue comprobaciones para el valor de retorno de memblock_alloc*()")
A static_command_line memory overflow was found in the Linux kernel. This issue may cause a crash.
