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...

SUSE CVE-2026-74344

In the Linux kernel, the following vulnerability has been resolved: bpf: Clear rb node linkage when freeing bpfrbroot bpfrbrootfree detaches the root by copying the current rbrootcached and then replacing the live root with RBROOTCACHED. It then walks the copied root and drops each object contain...

SUSE CVE-2026-74335

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL pointer dereference in bpftaskfromvpid bpftaskfromvpid looks up a task in the pid namespace of the current task, via findtaskbyvpid: findtaskbyvpidvpid findtaskbypidnsvpid, taskactivepidnscurrent findpidnsnr, ns -...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed NULL pointer dereferencing in bpftaskfromvpid. bpftaskfromvpid looks up a task in the pid namespace of the current task, via findtaskbyvpid: c findtaskbyvpidvpid findtaskbypidnsvpid, taskactivepidnscurrent...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: - bpf: Take the mmaplock in zappages zapvmarange requires that the owning memory manager’s mmaplock is held. Taking the mmapreadlock under arena-lock would lead to a race condition with arenavmclose and arenamapmmap. Both thes...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Clears the rb node linkage when freeing bpfrbroot. The bpfrbrootfree function detaches the root by copying the current rbrootcached, and then replacing the live root with RBROOTCACHED. It then walks the copied root and...

CVE-2026-74344

A flaw was found in the BPF Berkeley Packet Filter subsystem of the Linux kernel. When freeing a BPF red-black tree root, the system could leave behind stale pointers in certain objects. If the memory address is reused, a subsequent operation could incorrectly access these stale pointers, leading...

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...
