Short explanation
The wifi: iwlegacy: 3945 driver in the Linux kernel fails to free EEPROM data when a PCI device is removed, resulting in a memory leak.
This memory leak vulnerability was discovered through manual code inspection and affects memory management during hardware removal procedures.
What should be done?
- Follow the vendor advisory
- Free EEPROM data within il3945_pci_remove()
Chain of evidence and sources
Linux çekirdeğinde il3945_pci_probe() fonksiyonu EEPROM verileri için bellek tahsis eder.
Kaldırma yolu başarılı bir probe sonrasında EEPROM verilerini serbest bırakmaz ve bellek sızıntısına neden olur.
Show the technical text from the sources
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.
