Tested Mageia 9 on a junk Dell Latitude 5310: SATA RAID hides the NVMe, BIOSConnect fakes USB boot failure, ifcfg-rh keeps Wi-Fi unmanaged until keyfile migration.
Fragnesia (CVE-2026-46300) overwrites the Linux page cache via XFRM ESP-in-TCP. The Dirty Frag workaround still applies, but IPsec hosts need to check side effects first.
Dirty Frag is a local privilege escalation that writes to the Linux page cache via ESP-in-UDP and RxRPC receive paths. The algif_aead workaround from Copy Fail doesn't help, and the two attack paths complement each other to bypass Ubuntu's AppArmor restrictions on user namespaces.
CVE-2026-31431 Copy Fail is a Linux kernel local privilege escalation bug that lets an unprivileged user write 4 controlled bytes into the page cache via AF_ALG + algif_aead. On containers and CI runners it turns into host compromise.
Based on the 2025 Maintainers Summit consensus, coding-assistants.rst was merged into the Linux kernel, establishing rules for AI-assisted contributions: no Signed-off-by for AI, Assisted-by tag attribution, and full human responsibility.
Linux kernel 7.0-rc removes PREEMPT_NONE, causing a ~49% PostgreSQL throughput regression. The scheduler maintainer refuses to revert the change, demanding PostgreSQL adopt the new RSEQ timeslice extension instead. Ubuntu 26.04 LTS ships with this kernel.
An Anthropic researcher used Claude Code to scan the entire Linux kernel source and unearthed a 23-year-old remotely exploitable heap overflow in NFSv4.0. Technical breakdown plus a reality check on what it costs for ordinary users to replicate this.
