  "details": "In the Linux kernel, the following vulnerability has been resolved:  kexec: derive purgatory entry from symbol  kexec_load_purgatory() derives image-\u003estart by locating e_entry inside an SHF_EXECINSTR section.  If the purgatory object contains multiple executable sections with overlapping sh_addr, the entrypoint check can match more than once and trigger a WARN.  Derive the entry section from the purgatory_start symbol when present and compute image-\u003estart from its final placement.  Keep the existing e_entry fallback for purgatories that do not expose the symbol.
