stmmac driver

The Linux kernel vulnerability tracked as CVE-2025-38126 is a narrow but important robustness bug in the STMMAC Ethernet driver: under certain board or device-tree configurations the driver can end up with a zero PTP clock rate (ptp_rate / clk_ptp_rate), and that zero value may be used during...

The Linux kernel received a targeted fix for a subtle but consequential networking error: CVE-2025-40337 corrects how the stmmac Ethernet driver handles Rx checksum offload results so that packets for which the hardware reported checksum failures are no longer marked as valid and passed up the...

The Linux kernel fix tracked as CVE-2025-38125 corrects a simple but dangerous logic error in the STMMAC Ethernet driver: if the driver’s recorded ptp_rate is zero, that bogus value can be propagated into the EST configuration and cause a division‑by‑zero. Microsoft’s public advisory names Azure...
