Type	Values Removed	Values Added
Description		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.

details : [ »

0 : 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. (string)
