CVE-2026-43484

A flaw was found in the Linux kernel's MultiMediaCard MMC core. Concurrent updates to bitfield flags, specifically 'claimed' and 'retunenow', can lead to unintended overwrites of other bits in asynchronous contexts. This can trigger spurious warnings and result in system instability or unexpected...

CVE-2026-43486

CVE-2026-43486 – Linux kernel (arm64 contpte) details: The issue arises from contpte_ptep_set_access_flags() using a gathered ptep_get() to detect no-ops, which, in CONT ranges, can misreport a target as updated when a sibling sub-PTE still has PTE_RDONLY or lacks PTE_AF. This can trigger false n...

ExploitBench: A Capability Ladder Benchmark for LLM Cybersecurity Agents

Exploitation is not a binary event. It is a ladder of acquiring progressive capabilities, from executing a single buggy line of code to taking full control of the target. However, existing LLM security benchmarks treat a crash as exploitation success. That single binary outcome collapses the hard...
