CVE-2023-23002: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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).

Affected products

• Linux Linux Kernel: before 5.16.3 (fixed in 5.16.3)
