CVE-2026-46033

A flaw was found in the Linux kernel's authencesn cryptographic module. This vulnerability arises from insufficient validation of cryptographic digest sizes during the creation of new instances. A local attacker could exploit this by providing a malformed input, leading to an out-of-bounds memory...

CVE-2026-46033

In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject short ahash digests during instance creation authencesn requires either a zero authsize or an authsize of at least 4 bytes because the ESN encrypt/decrypt paths always move 4 bytes of high-order sequen...

CVE-2026-46033

CVE-2026-46033 affects the Linux kernel crypto/authencesn path. The flaw allowed authenc esn instances to inherit an invalid default authsize (digest sizes 1–3) because crypto_authenc_esn_create() copied digestsize into inst->alg.maxauthsize without validation, while setauthsize() already reje...
