How to check
- Find out whether you run the affected product and which version, then compare it with the versions above.
How to fix
Copies a prompt for Claude Code, Cursor or Codex that asks it to check whether you run this product.
- Apply the vendor's update or mitigation from the references below. If there is none yet, limit exposure of the affected service until there is.
- If a vulnerable version was live, check your logs and rotate the secrets that server could read.
The advisory
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Disable EOP for TPA on all chips to prevent data corruption
EOP (End of frame padding) on the AGG ring may cause overlapping of
zero padding at the end of one segment with the next segment's data.
If Relaxed Ordering (RO) is enabled, the zero padding may overwrite
valid data in the next segment and corrupt the data. Older chips
(P5 and older) do not automatically disable RO when EOP is enabled.
On some ARM systems, data corruption was reported on 57508 (P5)
chips with RO enabled.
Always disable EOP on all chips on the AGG rings when TPA is enabled
to fix the data corruption.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
