Zebra security vulnerabilities

Zebra is an open-source Zcash implementation built with Rust by the Zcash Foundation. Versions of Zebra prior to 4.4.0 contained security vulnerabilities; these vulnerabilities stemmed from the block verifier underestimating the number of transparent signature operations, which could lead to...

SUSE CVE-2026-6420

A flaw was found in Keylime. An attacker with root access on an enrolled monitored machine, where the Keylime agent runs, can exploit a vulnerability in the Keylime verifier. The verifier uses a hardcoded challenge nonce for Trusted Platform Module TPM quote attestation instead of a...

bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...

CVE-2026-6420

CVE-2026-6420 affects Keylime: a flaw in the verifier uses a hardcoded TPM quote nonce instead of a cryptographically random value. An attacker with root on an enrolled monitored machine where the Keylime agent runs can stockpile valid TPM quotes and replay them to evade detection after compromis...

CVE-2026-43070

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier fails to correctly reset a register's ID after a BPFEND byte swap operation. This oversight can lead to the verifier incorrectly propagating learned memory bounds to other registers, creating false confidence...

SUSE CVE-2026-43070

In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPFEND value tracking When a register undergoes a BPFEND byte swap operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register e.g., after an r1...

SOCpilot: Verifying Policy Compliance for LLM-Assisted Incident Response

Security operations centers SOCs are beginning to use large language models LLMs as copilots to draft incident-response plans. These plans may include actions that are valid per the catalog but still violate mandatory steps, required ordering, or approval gates before analyst review. SOCpilot mak...

EUVD-2026-27373

In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPFEND value tracking When a register undergoes a BPFEND byte swap operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register e.g., after an r1...

CVE-2026-43070

The CVE describes a Linux kernel BPF verifier flaw: after a BPF_END (byte swap), dst_reg->id is not reset to 0, which can cause the verifier to propagate learned bounds to a linked register, creating a risk of out-of-bounds memory accesses. The concrete impact is potential privilege/escalation...
