CVE-2026-98075

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When a BPF program references its main function as a callback, the kernel fails to translate the function reference into a valid memory address. A local user with permissions to load BPF programs could exploit this...

CVE-2026-98065

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local user can cause a Denial of Service DoS by creating a hash map lacking key type information and reading it through the BPF file system. Due to missing validation of BPF Type Format BTF metadata, the kernel attempt...

CVE-2026-98059

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This issue allows a local attacker to cause a Denial of Service DoS through a system crash. The vulnerability occurs because the BPF verifier fails to recognize that process-wait tracepoint arguments can be null,...

CVE-2026-98058

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Certain internal helper functions that pause execution to perform blocking operations were not properly marked as sleepable. A local user with permissions to load BPF programs can invoke these functions within...

CVE-2026-98045

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Certain stack retrieval helper functions can perform blocking filesystem operations, but were not properly marked as sleepable. A local user with permission to load BPF programs could exploit this flaw by invoking these...

CVE-2026-98038

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When validating programs that manage shared reference-counted objects, the BPF verifier incorrectly treats borrowed references as always valid and fails to require null-pointer checks. A local user can exploit this...

CVE-2026-98036

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local user with permission to run BPF programs can trigger a use-after-free condition, potentially leading to a system crash, denial of service DoS, or privilege escalation. This flaw occurs during the recycling of...

CVE-2026-98035

A flaw was found in the Linux kernel's BPF subsystem. When updating or deleting elements in resizable hash tables, the kernel directly releases special object fields rather than safely deferring their cancellation, which is not safe when running in Non-Maskable Interrupt NMI context. A local user...

CVE-2026-98033

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The kernel's program verifier improperly resets tracking identifiers when preparing callback functions, causing it to confuse different internal data structures sharing the same template. A local user with permission to...

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...
