In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed pointer-leak due to insufficient speculative store bypass mitigation To mitigate Spectre v4, the patch 2039f26f3aca “bpf: Fixed leakage due to insufficient speculative store bypass mitigation” includes instructions...

Astra Linux – Vulnerability in Xen

Potential speculative code storage bypasses exist in all supported CPU products. Combined with software vulnerabilities related to speculative execution of overwritten instructions, this could lead to incorrect speculation and potentially cause data leakage...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel up to version 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory through a Speculative Store Bypass side-channel attack. This occurs because a certain preempting store operation does not necessarily occur before a store operation whose valu...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel up to version 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory through a Speculative Store Bypass side-channel attack, because the protection mechanism ignores the possibility of uninitialized memory locations within the BPF stack...

CVE-2025-11850

When secondary user stores are configured, the implicit-association resolver incorrectly initializes from a secondary user store and bypasses the primary user store during search and uniqueness checks. This allows a subject to be associated with an unintended local account if the same lookup clai...

undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy

A flaw was found in undici. When undici's ProxyAgent is configured with a SOCKS5 proxy Uniform Resource Identifier URI, it silently ignores Transport Layer Security TLS options, such as custom Certificate Authorities CAs. This allows a remote attacker to perform a Man-in-the-Middle MITM attack,...

CVE-2026-11310

X.509 trust-chain bypass in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra OPENSSLEXTRA and whose application validates certificates by calling X509verifycert with caller-supplied untrusted intermediate certificates; for...
