CVE-2026-90217

This Linux kernel BPF verifier vulnerability (CVE-2026-90217) occurs because an iterator stack slot can hold either MEM_RCU or PTR_UNTRUSTED pointer types, and the verifier fails to distinguish them during state pruning, potentially pruning an unsafe path. The fix compares the pointer type for ST...

CVE-2026-90217 bpf: Compare iterator types during state pruning

In the Linux kernel, the following vulnerability has been resolved: bpf: Compare iterator types during state pruning An iterator stack slot can be MEMRCU or PTRUNTRUSTED. These states must not be equal, or the verifier can prune an unsafe path. Compare the pointer type for STACKITER slots...

OESA-2026-3705 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: ocfs2/dlm: fix off-by-one in dlmmatchregions region comparison The local-vs-remote region comparison loop uses '=' instead of '', causing it to read one entry pa...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

Incorrect verifier pruning in the BPF module of the Linux kernel version 5.4 and above leads to unsafe code paths being incorrectly marked as safe. This results in arbitrary read/writes to kernel memory, lateral privilege escalation, and container escapes...

kernel: ixgbevf: fix use-after-free in VEPA multicast source pruning

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

CVE-2026-58484 Network-AI: Poisoned environment backup manifest allows arbitrary recursive deletion during backup pruning

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, EnvironmentManager.listBackups reads each backup's manifest.json and trusts the manifest's path field. EnvironmentManager.pruneBackups later passes that trusted entry.path directly to rmSyncentry.path, recursive...

PT-2026-61430

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the ixgbevf driver during VEPA multicast source pruning. The function ixgbevf clean rx irq frees a socket buffer skb and continues to the next descriptor...

CVE-2026-53081

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs due to inconsistent base ID mapping when the regsafe function compares scalar registers with BPFADDCONST values. This inconsistency allows the BPF verifier to incorrectly succeed in state pruning...
