CVE-2010-4242

no score yetEPSS 0.5%

The hci_uart_tty_open function in the HCI UART driver (drivers/bluetooth/hci_ldisc.c) in the Linux kernel 2.6.36, and possibly other versions, does not verify whether the tty has a write operation, which allows local users to cause a denial of service (NULL pointer dereference) via vectors related to the Bluetooth driver.

EPSS: 0.5% chance of exploitation in the next 30 days; higher than 39% of CVEs (scores of 2026-10-31)
