USN-8388-2: Linux kernel vulnerabilities

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

CVE-2026-47833

setupBpmLogs follows symlink for bpm.log open and chown — container-to-host privilege escalation via /etc/shadow. A compromised process inside a bpm container can cause root to chown an arbitrary host file to vcap and append bpm JSON log lines to it. The chown alone lets the attacker take ownersh...

One-Character Linux Kernel Flaw Enables Local Root Access, Exploits Now Public

Security researchers have published a detailed, working exploit for a Linux kernel use-after-free that lets an unprivileged local user escalate to root and break out of a container. The flaw, CVE-2026-23111, sits in the kernel's nftables packet-filtering code and was patched upstream on February ...
