CVE-2023-52898

16
FAUCET Score

CVE-2023-52898 is a null pointer dereference vulnerability in the Linux kernel's xHCI driver, affecting the 'linux_kernel' product. This flaw occurs due to a race condition when the USB host suddenly dies, allowing xhci_free_dev() to free a device while xhci_kill_endpoint_urbs() attempts to access its endpoints. Rated as MEDIUM severity (CVSS 4.7), it requires local access and high attack complexity, potentially leading to a denial of service. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
