Lifecycle Timeline
3DescriptionNVD
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtlwifi: fix memory leaks and invalid access at probe error path
Deinitialize at reverse order when probe fails.
When init_sw_vars fails, rtl_deinit_core should not be called, specially now that it destroys the rtl_wq workqueue.
And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be leaked.
Remove pci_set_drvdata call as it will already be cleaned up by the core driver code and could lead to memory leaks too. cf. commit 8d450935ae7f ("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and commit 3d86b93064c7 ("rtlwifi: Fix PCI probe error path orphaned memory").
AnalysisAI
In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: fix memory leaks and invalid access at probe error path Deinitialize at reverse order when probe fails. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Technical ContextAI
This vulnerability is classified as Memory Leak (CWE-401), which allows attackers to exhaust available memory leading to denial of service. In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: fix memory leaks and invalid access at probe error path Deinitialize at reverse order when probe fails. When init_sw_vars fails, rtl_deinit_core should not be called, specially now that it destroys the rtl_wq workqueue. And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be leaked.

Affected products include: Linux Linux Kernel.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Ensure all allocated memory is properly freed. Use RAII patterns or garbage-collected languages.
