CVE-2022-50765

CVE-2022-50765 affects the Linux kernel (RISC‑V) in the kexec path. The root cause is a memory leak: a buffer used to store ELF headers is allocated with vzalloc() during elf_kexec_load and is not freed when the kdump kernel is reloaded/unloaded or when image->elf_header is set and loading sub...
