- Summary
- CVE-2024-56745 affecting package kernel for versions less than 5.15.176.3-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix resetmethodstore() memory leak
In resetmethodstore(), 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.
