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.

Affected configurations

• linux linux kernel (>= 4.3 < 5.10.249) • linux linux kernel (>= 5.11 < 5.15.199) • linux linux kernel (>= 5.16 < 6.1.162) • linux linux kernel (>= 6.2 < 6.6.122) • linux linux kernel (>= 6.7 < 6.12.68) • linux linux kernel (>= 6.13 < 6.18.8) • linux linux kernel 6.19
