CVE-2026-98275: net: ethernet: cortina: Ack RX overrun interrupt correctly

—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 1163cc82dcbc145f912bf2106ab668762f53e483, 12a0c7bb448c1899ea3d8f97fa47a8740044e16d, 1dd85662fee6e2ac580b1c4f9a0c0a7ae6e31f0e; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.

Low priority for now. Upgrade to Linux Linux 1163cc82dcbc145f912bf2106ab668762f53e483, 12a0c7bb448c1899ea3d8f97fa47a8740044e16d, 1dd85662fee6e2ac580b1c4f9a0c0a7ae6e31f0e; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Ack RX overrun interrupt correctly The RX overrun interrupt is reported in interrupt status register 4, but gmac_irq() acknowledges it using the RX descriptor error bit from status register 0. For GMAC0 this writes the GMAC1 overrun bit, while for GMAC1 the shift leaves no bit in the 32-bit register. Acknowledge the same per-port RX overrun bit that was detected.
