In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
x86\/amd_node: Fix PCI device reference counting in amd_smn_init()<\/p>\n
The local “root” pointer is a temporary variable used during the device
\nsearch. Therefore, refcount related to the search iterators should be cleaned
\nup after the search is complete.<\/p>\n
Use the __free() cleanup macro to ensure the refcount is decremented when the
\ntemporary pointer goes out of scope.<\/p>\n
Additionally, increment the refcount when caching a root pointer. This ensures
\nthe in-use refcount is separate from the temporary search refcounting.<\/p>\n
Finally, drop the redundant “root = NULL” before the second search loop. The
\npci_get_class() iterator always decrements the refcount of its “from”
\nargument, so the first loop can only fall through with “root” already NULL.<\/p>\n","protected":false},"excerpt":{"rendered":"
