CVE-2026-23060
crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec authencesn assumes an ESP/ESN-formatted AAD. When assoclen is shorter than the minimum expected length, crypto_authenc_esn_decrypt() can advance past the end of the destination scatterlist and trigger a NULL pointer dereference in scatterwalk_map_and_copy(), leading to a kernel panic (DoS). Add a minimum AAD length check to fail fast on invalid inputs.

|---|---|---|---|---|---|---|
| CVSS 3.1 | MEDIUM | [email protected] |
Solution
- Add minimum AAD length check for crypto_authenc_esn_decrypt.
- Ensure AAD length is at least 8 bytes.
- Reject invalid inputs to prevent DoS.
- Update kernel to include the fix.
