In the Linux kernel, the following vulnerability has been resolved:
efi/capsule-loader: fix incorrect allocation size gcc-14 notices that the
allocation with sizeof(void) on 32-bit architectures is not enough for a
64-bit phys_addr_t: drivers/firmware/efi/capsule-loader.c: In function
‘efi_capsule_open’: drivers/firmware/efi/capsule-loader.c:295:24: error:
allocation of insufficient size ‘4’ for type ‘phys_addr_t’ {aka ‘long long
unsigned int’} with size ‘8’ [-Werror=alloc-size] 295 | cap_info->phys =
kzalloc(sizeof(void *), GFP_KERNEL); | ^ Use the correct type instead here.
