Description
In the Linux kernel, the following vulnerability has been resolved:
powerpc/rtas: Prevent Spectre v1 gadget construction in sys_rtas()
Smatch warns:
arch/powerpc/kernel/rtas.c:1932 __do_sys_rtas() warn: potential
spectre issue 'args.args' [r] (local cap)
The 'nargs' and 'nret' locals come directly from a user-supplied
buffer and are used as indexes into a small stack-based array and as
inputs to copy_to_user() after they are subject to bounds checks.
Use array_index_nospec() after the bounds checks to clamp these values
for speculative execution.
Affected configurations
• linux linux kernel (< 6.10.10)
