CVE-2026-90403

Estado: RecibidaAlta (7)—

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtlwifi: pci: fix error path in rtl_pci_probe()

In the last error path in rtl_pci_probe(), the cleanup functions are skipped due to a wrong goto label. Moreover, the successful call to rtl_init_rfkill(), ieee80211_register_hw(), rtl_debug_add_one() have to be reverted. Fix this issue by updating the labels and adding the relevant cleanup functions to the last error path.
