CVE-2026-80992
|
| Sažetak |
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. |
