Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fixed the issue where unrecoverable MCE calls the async handler from NMI. The machine check handler is not considered NMI on 64s. The earlier handler is the actual NMI handler; it schedules the machinecheckexception...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: EDAC/mc: Fixed the error path ordering in edacmcalloc. When the mci-pvtinfo allocation in edacmcalloc fails, the error path will call putdevice, which will ultimately call the device’s release function. However, the initializatio...

Towards Remote Attestation of Microarchitectural Attacks: The Case of Rowhammer

Microarchitectural vulnerabilities increasingly undermine the assumption that hardware can be treated as a reliable root of trust. Prevention mechanisms often lag behind evolving attack techniques, leaving deployed systems unable to assume continued trustworthiness. We propose a shift from...
