DEBIAN-CVE-2026-84308
phpseclib is a PHP secure communications library. Prior to 3.0.57 and 4.0.1, pure-PHP X25519 scalar multiplication in phpseclib/Math/PrimeField/Integer.php performs data-dependent conditional modular reductions in add and subtract. During the Montgomery ladder in...
CVE-2026-84308 phpseclib — non-constant-time X25519 scalar multiplication permits full private-key recovery
phpseclib is a PHP secure communications library. Prior to 3.0.57 and 4.0.1, pure-PHP X25519 scalar multiplication in phpseclib/Math/PrimeField/Integer.php performs data-dependent conditional modular reductions in add and subtract. During the Montgomery ladder in...
CVE-2026-84308
phpseclib , a PHP secure communications library, has a non-constant-time X25519 scalar multiplication flaw in versions prior to 3.0.57 and 4.0.1 . The root cause is data-dependent conditional modular reductions in the pure-PHP implementation (Math/PrimeField/Integer.php), which leak per-step timi...

CVE-2026-54496
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad 5.0.0, halo2gadgets 0.5.0, orchard 0.14.0, zcashprimitives 0.28.0, and zcashd 6.20.0, the variable-base scalar multiplication gadget in halo2gadgets/src/ecc/chip/mul/incomplete.rs used assignadvice for the base point without a copy...
CVE-2026-54496
CVE-2026-54496 affects Zebrad and related crates (halo2_gadgets, orchard, zcash_primitives, zcashd) prior to fixed versions. Root cause: the variable-base scalar multiplication gadget uses assign_advice() to feed the base point in halo2_gadgets—without a copy constraint tying it to the real base—...
CVE-2026-10512
The X25519 x8664 assembly implementation fails to clear the most significant bit during the final modular reduction, so the computed result may not be fully reduced modulo the field prime 2^255 - 19. This can leave the field element in a non-canonical form, producing an incorrect result from the...
CVE-2026-3580
In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover secret...

CVE-2026-26958
A flaw was found in filippo.io/edwards25519, a Go library used for cryptographic operations. This vulnerability occurs in the MultiScalarMult function when it processes points that are not properly initialized or are not the identity point. Such conditions can lead to incorrect cryptographic...
UBUNTU-CVE-2026-26958
filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If Point.MultiScalarMult i...
GO-2026-4503 Invalid result or undefined behavior in filippo.io/edwards25519
Previously, if MultiScalarMult was invoked on an initialized point who was not the identity point, MultiScalarMult produced an incorrect result. If called on an uninitialized point, MultiScalarMult exhibited undefined behavior...
