CVE-2026-43289

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> kexec: derive purgatory entry from symbol<br /> <br /> kexec_load_purgatory() derives image-&gt;start by locating e_entry inside an<br /> SHF_EXECINSTR section. If the purgatory object contains multiple<br /> executable sections with overlapping sh_addr, the entrypoint check can<br /> match more than once and trigger a WARN.<br /> <br /> Derive the entry section from the purgatory_start symbol when present and<br /> compute image-&gt;start from its final placement. Keep the existing e_entry<br /> fallback for purgatories that do not expose the symbol.<br /> <br /> WARNING: kernel/kexec_file.c:1009 at kexec_load_purgatory+0x395/0x3c0, CPU#10: kexec/1784<br /> Call Trace:<br /> <br /> bzImage64_load+0x133/0xa00<br /> __do_sys_kexec_file_load+0x2b3/0x5c0<br /> do_syscall_64+0x81/0x610<br /> entry_SYSCALL_64_after_hwframe+0x76/0x7e<br /> <br /> [me@linux.beauty: move helper to avoid forward declaration, per Baoquan]
