Upstream information
Description
In the Linux kernel, the following vulnerability has been resolved:resource,kexec: walk_system_ram_res_rev must retain resource flags
walk_system_ram_res_rev() erroneously discards resource flags when passing
the information to the callback.
This causes systems with IORESOURCE_SYSRAM_DRIVER_MANAGED memory to have
these resources selected during kexec to store kexec buffers if that
memory happens to be at placed above normal system ram.
This leads to undefined behavior after reboot. If the kexec buffer is
never touched, nothing happens. If the kexec buffer is touched, it could
lead to a crash (like below) or undefined behavior.
Tested on a system with CXL memory expanders with driver managed memory,
TPM enabled, and CONFIG_IMA_KEXEC=y. Adding printk's showed the flags
were being discarded and as a result the check for
IORESOURCE_SYSRAM_DRIVER_MANAGED passes.
