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 physaddrt:
drivers/firmware/efi/capsule-loader.c: In function 'eficapsuleopen': drivers/firmware/efi/capsule-loader.c:295:24: error: allocation of insufficient size '4' for type 'physaddrt' {aka 'long long unsigned int'} with size '8' [-Werror=alloc-size] 295 | capinfo->phys = kzalloc(sizeof(void *), GFPKERNEL); | ^
Use the correct type instead here.
