RUSTSEC-2026-0385 Non-constant-time mask generation and `u128` comparisons

Summary The ctutils::Choice type has mask generation functions for each unsigned integer size u8, u16, u32, u64, u128. These are const fn and therefore can't reuse the asm!-backed mask generation in the cmov crate that's otherwise used to ensure constant-time. In releases prior to v0.4.4, the...

CVE-2026-18036 NTRU leaks private key information by reducing secret values with a non-constant-time integer division

In Bouncy Castle for Java before 1.86, NTRU reduced secret values with the % operator in three helpers whose reference implementations are deliberately division-free, so each reduction was carried out by an integer division whose latency depends on the secret operand. Polynomial.modQ divided by a...

openssl: openssl: information disclosure via non-constant-time SM2 scalar multiplication on ARM64 and RISC-V

A flaw was found in OpenSSL. The optimized scalar point multiplication used for SM2 cryptographic operations on ARM64 and RISC-V architectures does not execute in constant time. An attacker capable of measuring execution times or observing processor cache-access patterns can exploit this side...

AZL-105861 CVE-2026-77696 affecting package rust 1.96.1-2

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn information about the per-signature secret nonce, which over many signatures can, via a lattice / Hidd...

GHSA-38P6-H87P-R4CG Grav: Non constant time nonce comparison in Utils::verifyNonce() used for CSRF protection

Summary Grav\Common\Utils::verifyNonce, the core function Grav and its plugins use to validate CSRF nonces, compares the submitted nonce to the expected value with PHP's === operator instead of hashequals. === on strings short circuits at the first differing byte, so the comparison time leaks how...
