CVE-2023-53644
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
media: radio-shark: Add endpoint checks
The syzbot fuzzer was able to provoke a WARNING from the radio-shark2 driver:
The problem was caused by the fact that the driver does not check whether the endpoints it uses are actually present and have the appropriate types. This can be fixed by adding a simple check of these endpoints (and similarly for the radio-shark driver).
