What is CVE-2026-98710?
CVE-2026-98710 is a memory corruption vulnerability in Linux, published on 18 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
