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:
soundwire: fix bug in sdw_add_element_group_count found by syzkaller
The original implementation caused an out-of-bounds memory access
in the sdw_add_element_group_count for-loop when i == num.
for (i = 0; i <= num; i++) {
if (rate == group->rates[i] && lane == group->lanes[i])
...
To fix this error, the function now checks for existing rate/lane
entries in the group(a function parameter) using a for-loop before
adding them.
No functional changes apart from this fix.
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.
