Loading vulnerability…
CVE-2024-57987 is a NULL-pointer dereference in the Linux kernel Bluetooth Realtek (btrtl) driver. In btrtl_setup_realtek(), processing a USB Bluetooth dongle whose chip identifier is not represented in the driver’s supported identifier table can yield a NULL lookup result that is subsequently dereferenced. The upstream correction validates the lookup result before use, preventing the kernel Oops.

Linux kernel Bluetooth Realtek setup NULL-pointer flaw.
A Linux kernel Bluetooth Realtek (btrtl) driver NULL-pointer dereference in btrtl_setup_realtek(). Connecting a USB Bluetooth dongle whose chipset is absent from ic_id_table can trigger a kernel Oops; the fix adds a NULL check.
A moderate-severity Linux kernel Bluetooth Realtek (btrtl) NULL-pointer dereference vulnerability. A local authenticated attacker can trigger a denial of service through a crash or restart; Red Hat assigns CVSS 5.5.
A Linux kernel Bluetooth Realtek (btrtl) driver NULL-pointer dereference. Connecting a USB Bluetooth dongle whose chip is absent from ic_id_table can trigger a kernel Oops. The issue was introduced in Linux kernel 6.10 and is fixed in 6.12.13, 6.13.2, and 6.14-rc1.
