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...

CVE-2026-89580

In the Linux kernel, the following vulnerability has been resolved: bpf: Disable preemption in bpfgetstack getperfcallchain returns a per-CPU perfcallchainentry buffer and releases its recursion slot via putcallchainentry before returning, so nothing keeps the entry reserved while bpfgetstack...

A deadlock flaw was discovered in the Linux kernel’s BPF subsystem. This flaw allows a local user to potentially crash the system...

CVE-2026-74335

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs in the bpftaskfromvpid function when a cgroupskb program, running in a soft interrupt, attempts to look up a task that is in the process of exiting. If the task's process ID PID namespace is...

CVE-2026-74337

A flaw was found in the Linux kernel, specifically within the BPF Berkeley Packet Filter subsystem. This vulnerability allows NMI Non-Maskable Interrupt and tracepoint BPF programs to re-enter certain internal locks, known as LRU Least Recently Used locks, while they are already held. This re-ent...

CVE-2026-74258

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A missing bounds check when accessing user space data for uprobemulti could allow a local attacker to read or write to memory outside of intended boundaries. This vulnerability can lead to information disclosure or...

CVE-2026-74354

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could exploit a locking issue within the zappages function. This vulnerability arises because zapvmarange requires a specific memory map lock mmaplock that, when acquired under certain conditions, can le...

CVE-2026-74314

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This vulnerability arises from improper handling of special fields during the recycling of map values, which can lead to unsafe destruction operations. Specifically, in tracing programs operating within a Non-Maskable...

CVE-2026-72426

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The cleanfuncstate function, which manages stack slot cleanup, incorrectly clears metadata for pointer spills. This allows a subsequent read from a partially live stack slot to bypass crucial non-scalar register-fill...
