CVE-2026-98710 PUBLISHED

wifi: iwlegacy: 3945: free EEPROM data on remove

Assigner: Linux
Reserved: 25.09.2026 Published: 18.10.2026 Updated: 18.10.2026

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

wifi: iwlegacy: 3945: free EEPROM data on remove

il3945_pci_probe() calls il_eeprom_init(), which allocates memory for the EEPROM data. The probe failure paths release this allocation with il_eeprom_free(), but the remove path does not free it after a successful probe.

As a result, the EEPROM data is leaked when the PCI device is removed.

Free the EEPROM data in il3945_pci_remove() before releasing the mac80211 hardware structure.

This issue was found by manual code inspection.
