In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix reset_method_store() memory leak
In reset_method_store(), a string is allocated via kstrndup() and assigned
to the local "options". options is then used in with strsep() to find
spaces:
while ((name = strsep(&options, " ")) != NULL) {
If there are no remaining spaces, then options is set to NULL by strsep(),
so the subsequent kfree(options) doesn't free the memory allocated via
kstrndup().
Fix by using a separate tmp_options to iterate with strsep() so options is
preserved. |
