CVE-2024-43840

CVE-2024-43840 – Linux kernel (arm64, BPF trampoline) : The trampoline code for BPF_TRAMP_F_CALL_ORIG incorrectly used emit_addr_mov_i64(), assuming the bpf_tramp_image address resides in vmalloc() space with 48-bit handling. If the address exceeds 48 bits (e.g., kzalloc’d bpf_tramp_image), the t...

CVE-2024-43868

CVE-2024-43868 is a Linux kernel flaw in the riscv purgatory alignment path. When alignment handling is delegated to the kernel, purgatory must keep all addresses word-aligned because the kexec trap handler is used.
