CVE-2022-49368
Estado: ModificadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_eth_soc: out of bounds read in mtk_hwlro_get_fdir_entry()
The "fsp->location" variable comes from user via ethtool_get_rxnfc(). Check that it is valid to prevent an out of bounds read.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.28%
- Percentil entre todas las CVEs puntuadas: 19
- Fecha de la puntuación: 5/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
🎯 Técnicas ATT&CK
