thermal: gov_power_allocator: Add missing NULL pointer check

2025-03-07T17:25:46+00:00

commit ac1f43c03fc91eee53cc95683245350d4d87781e upstream. Commit 0dc23567c206 ("thermal: core: Move lists of thermal instances to trip descriptors") overlooked the case in which the Power Allocator governor attempts to bind to a tripless thermal zone and params->trip_max is NULL in check_power_actors(). No power actors can be found in that case, so check_power_actors() needs to be made return 0 then to restore its previous behavior. Fixes: 0dc23567c206 ("thermal: core: Move lists of thermal instances to trip descriptors") Closes: https://lore.kernel.org/linux-pm/Z0NeGF4ryCe_b5rr@sashalap/ Reported-by: Sasha Levin Signed-off-by: Rafael J.

x86/microcode/AMD: Load only SHA256-checksummed patches

2025-03-07T17:25:46+00:00

commit 50cef76d5cb0e199cda19f026842560f6eedc4f7 upstream. Load patches for which the driver carries a SHA256 checksum of the patch blob. This can be disabled by adding "microcode.amd_sha_check=off" on the kernel cmdline. But it is highly NOT recommended. Signed-off-by: Borislav Petkov (AMD) Signed-off-by: Greg Kroah-Hartman
