Last modified
CVE-2023-23002 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel before 5.16.3, drivers/bluetooth/hci_qca.c misinterprets the devm_gpiod_get_index_optional return value (expects it to be NULL in the error case, whereas it is actually an error pointer).. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
