CVE-2024-58063: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-58063 is a vulnerability discovered in the Linux kernel's rtlwifi driver component. The issue was identified and resolved in March 2025, affecting the memory management in the probe error path of the rtlwifi driver. The vulnerability specifically impacts the Realtek wireless driver implementation in the Linux kernel (NVD, RedHat).

The vulnerability involves memory leaks and invalid access in the probe error path of the rtlwifi driver. The issue occurs when initialization fails, specifically when init_sw_vars fails, where rtl_deinit_core was being called incorrectly, leading to potential issues with the rtl_wq workqueue. The vulnerability also involves improper cleanup of PCI driver data that could lead to memory leaks. The CVSS v3.1 score for this vulnerability is 5.5 (Low) with a vector of AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (RedHat).

The vulnerability can result in memory leaks and invalid memory access in the Linux kernel's rtlwifi driver. This could potentially lead to system instability or denial of service conditions when the affected driver component fails to initialize properly (NVD).

The issue has been resolved through a patch that corrects the deinitialization order when probe fails. The fix includes proper cleanup procedures: removing unnecessary pci_set_drvdata calls, implementing correct deinitialization sequence, and ensuring proper memory cleanup. The patch has been integrated into various Linux kernel versions (Kernel Commit).
