Linux Distros Unpatched Vulnerability : CVE-2026-89580

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Disable preemption in bpfgetstack getperfcallchain returns a per-CPU perfcallchainentry buffer and releases its recursion slot via putcallchainentry before...

CVE-2026-89580

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local attacker could exploit a timing issue in the bpfgetstack function. This occurs when a preemptible BPF program is scheduled out, allowing another task to overwrite a per-CPU buffer. This leads to an out-of-bounds...
