The advisory
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: rtw_mlme: add bounds checks before ie_length subtraction
Add guards to ensure ie_length is large enough before subtracting
fixed IE offsets to prevent unsigned integer underflow.
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.
