Overview
CVE-2026-97981 is a known-severity vulnerability. It was published on September 25, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: cortina: Count dropped frames as NAPI work
The RX loop only consumes budget when it successfully delivers a frame.
Error paths keep consuming descriptors without reducing the budget, so a
stream of bad frames can process the entire receive ring in one poll.
Move the budget accounting to a common end-of-frame path. This counts
each completed frame as NAPI work whether it was delivered or dropped,
matching the behavior of the vendor driver.
