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*()”)
