CVE-2026-98585 in Linux
要約
〜によって MITRE • 2026年10月18日
In the Linux kernel, the following vulnerability has been resolved:
eth: fbnic: Avoid rounding zero ring sizes
roundup_pow_of_two() is undefined for zero. ethtool permits a zero ring size to reach the driver, where the minimum-size check should reject it.
Leave zero unchanged while rounding nonzero ring sizes. The minimum-size check then rejects zero deterministically without changing the established behavior for other values.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
