CVE-2025-37755 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: libwx: handle page_pool_dev_alloc_pages error page_pool_dev_alloc_pages could return NULL. There was a WARN_ON(!page) but it would still proceed to use the NULL pointer and then crash. This is similar to commit 001ba0902046 ("net: fec: handle page_pool_dev_alloc_pages error"). This is found by our static analysis tool KNighter.
A vulnerability in the Linux kernel's network subsystem related to page pool management has been identified. The issue arises in the 'libwx' component, where the function 'page_pool_dev_alloc_pages' could return a NULL pointer. Despite a warning indicating the absence of a valid page, the code would continue to use the NULL pointer, leading to a crash. This vulnerability is similar to a previously addressed issue in the 'fec' driver, where page allocation errors were not handled properly.
