CVE-2022-50170

In the Linux kernel, the following vulnerability has been resolved: kunit: executor: Fix a memory leak on failure in kunit_filter_tests It's possible that memory allocation for 'filtered' will fail, but for the copy of the suite to succeed. In this case, the copy could be leaked. Properly free 'copy' in the error case for the allocation of 'filtered' failing. Note that there may also have been a similar issue in kunit_filter_subsuites, before it was removed in "kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites". This was reported by clang-analyzer via the kernel test robot, here: https://lore.kernel.org/all/c8073b8e-7b9e-0830-4177-87c12f16349c@intel.com/ And by smatch via Dan Carpenter and the kernel test robot: https://lore.kernel.org/all/202207101328.ASjx88yj-lkp@intel.com/

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: kunit: executor: Se corrige una fuga de memoria en caso de fallo en kunit_filter_tests. Es posible que la asignación de memoria para "filtered" falle, pero que la copia de la suite se realice correctamente. En este caso, la copia podría sufrir una fuga. Libere correctamente "copy" en caso de error en caso de fallo en la asignación de "filtered". Tenga en cuenta que también podría haber existido un problema similar en kunit_filter_subsuites, antes de que se eliminara en "kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites". Esto fue informado por clang-analyzer a través del robot de pruebas del kernel, aquí: https://lore.kernel.org/all/c8073b8e-7b9e-0830-4177-87c12f16349c@intel.com/ Y por smatch a través de Dan Carpenter y el robot de pruebas del kernel: https://lore.kernel.org/all/202207101328.ASjx88yj-lkp@intel.com/
