CVE-2026-56101

OpenBSD before commit 1ee99df contains an inverted comparison vulnerability in the ieee80211michaelmicfailure function within sys/net80211/ieee80211cryptotkip.c that allows unauthenticated attackers within RF range to trigger denial of service by sending two malformed TKIP frames separated by mor...

CVE-2026-56101

OpenBSD before commit 1ee99df contains an inverted comparison in the ieee80211_michael_mic_failure() function within sys/net80211/ieee80211_crypto_tkip.c. The reversed TKIP MIC failure countermeasure window check allows unauthenticated attackers within RF range to send two malformed TKIP frames s...

JENGA: Exploiting Counter-Based RowHammer Countermeasures to Break Real-Time Predictability

Safety-critical real-time systems must satisfy multiple dependability requirements, notably time predictability and security. In such systems, tasks must complete within bounded and known execution times, typically characterised through Worst-Case Execution Time WCET analysis. At the same time,...

Practical Countermeasure against Attacks Exploiting Detection Efficiency Mismatch in Quantum Key Distribution

We demonstrate a practical countermeasure against a well-known class of attacks on quantum key distribution QKD systems that exploit detection efficiency mismatch, where the receiver's detectors do not exhibit identical responses to incoming photons across all degrees of freedom. This class of...

GhostWrite: New T-Head CPU Bugs Expose Devices to Unrestricted Attacks

A team of researchers from the CISPA Helmholtz Center for Information Security in Germany has disclosed an architectural bug impacting Chinese chip company T-Head's XuanTie C910 and C920 RISC-V CPUs that could allow attackers to gain unrestricted access to susceptible devices. The vulnerability h...

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

A flaw was found in the SSH channel integrity. By manipulating sequence numbers during the handshake, an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example, an attacker could disable the ping extension and thus disable the new countermeasure ...
