Vulnerability from github – Published: 2025-07-03 09:30 – Updated: 2026-01-11 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

net: stmmac: make sure that ptp_rate is not 0 before configuring EST

If the ptp_rate recorded earlier in the driver happens to be 0, this bogus value will propagate up to EST configuration, where it will trigger a division by 0.

Prevent this division by 0 by adding the corresponding check and error code.

Severity ?

5.5 (Medium)
