      "title": "module: decompress: check return value of module_extend_max_pages()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmodule: decompress: check return value of module_extend_max_pages()\n\nmodule_extend_max_pages() calls kvrealloc() internally and returns\n-ENOMEM on allocation failure. The return value is never checked.\n\nIf the initial allocation fails, info->pages remains NULL and\ninfo->max_pages remains 0. Subsequent calls to module_get_next_page()\nwill attempt to dynamically grow the array by calling\nmodule_extend_max_pages(info, 0) since info->used_pages is 0. This\nresults in kvrealloc(NULL, 0) returning ZERO_SIZE_PTR, which is treated\nas a success, leading to a dereference of ZERO_SIZE_PTR and a kernel\noops.\n\nFix: add the missing error check after module_extend_max_pages() and\nreturn immediately on failure. This matches the pattern used by every\nother kvrealloc() caller in the module loading path.\n\n[Sami: Corrected the analysis in the commit message.]",
