Warning: New RapperBot Campaign Aims to Launch DDoS Attacks at Game Servers

Cybersecurity researchers have unearthed new samples of malware called RapperBot that are being used to build a botnet capable of launching Distributed Denial of Service DDoS attacks against game servers. "In fact, it turns out that this campaign is less like RapperBot than an older campaign that...

kernel: iommu/arm-smmu-v3-sva: Fix mm use-after-free

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-sva: Fix mm use-after-free We currently call arm64mmcontextput without holding a reference to the mm, which can result in use-after-free. Call mmgrab/mmdrop to ensure the mm only gets freed after we unpinned the...
