Details
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*()")
