CVE-2026-80992
Resumen
por MITRE • 2026-09-12
In the Linux kernel, the following vulnerability has been resolved:
net: ravb: avoid dereferencing an invalid PTP clock
The PTP clock is unavailable before the first open, so querying its index can dereference a NULL pointer. Registration failures can also leave an error pointer in priv->ptp.clock.
Cache the PHC index separately and report -1 while no clock is registered. Normalize registration errors to NULL and preserve the static timestamping capabilities.
