  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ravb: avoid dereferencing an invalid PTP clock\n\nThe PTP clock is unavailable before the first open, so querying its\nindex can dereference a NULL pointer. Registration failures can also\nleave an error pointer in priv-\u003eptp.clock.\n\nCache the PHC index separately and report -1 while no clock is\nregistered. Normalize registration errors to NULL and preserve the\nstatic timestamping capabilities.",
