Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: net/tcpmd5: The comparison of MACs has been fixed to require constant time. To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper functions for this purpose...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper function for this purpose...
Astra Linux – Vulnerability in Heimdal
The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...
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...
