  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  module: decompress: check return value of module...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  module: decompress: check return value of module_extend_max_pages()  module_extend_max_pages() calls kvrealloc() internally and returns -ENOMEM on allocation failure. The return value is never checked.  If the initial allocation fails, info-\u003Epages remains NULL and info-\u003Emax_pages remains 0. Subsequent calls to module_get_next_page() will attempt to dynamically grow the array by calling module_extend_max_pages(info, 0) since info-\u003Eused_pages is 0. This results in kvrealloc(NULL, 0) returning ZERO_SIZE_PTR, which is treated as a success, leading to a dereference of ZERO_SIZE_PTR and a kernel oops.  Fix: add the missing error check after module_extend_max_pages() and return immediately on failure. This matches the pattern used by every other kvrealloc() caller in the module loading path.  [Sami: Corrected the analysis in the commit message.]",
