Last modified

CVE-2023-52507 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: nfc: nci: assert requested protocol is valid The protocol is used in a bit mask to determine if the protocol is supported. Assert the provided protocol is less than the maximum defined so it doesn't potentially perform a shift-out-of-bounds and provide a clearer error for undefined protocols vs unsupported ones.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
