Core Flight System security vulnerabilities

Core Flight System cFS is a generic flight software architecture framework open source by NASA. It is used for flagship spacecraft, manned spacecraft, cube satellites, and Raspberry Pi devices. Versions of Core Flight System 7.0.0 and earlier contain security vulnerabilities. These vulnerabilitie...

CVE-2026-5474: Heap-based Buffer Overflow

A vulnerability was found in NASA cFS up to 7.0.0. This affects the function CFEMSGGetSize of the file apps/tolab/fsw/src/tolabpassthruencode.c of the component CCSDS Packet Header Handler. Performing a manipulation results in heap-based buffer overflow. The attacker must have access to the local...

CVE-2026-23456: Out-of-bounds Read

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodeint CONS case In decodeint, the CONS case calls getbitsbs, 2 to read a length value, then calls getuintbs, len without checking that len bytes remain in the buffer. The existing...

PT-2026-30148

In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: Fix memory leak in XDP DROP for non-zero-copy mode Page recycling was removed from the XDP DROP path in emac run xdp to avoid conflicts with AF XDP zero-copy mode, which uses xsk buff free instead. However,...

CVE-2026-23412

A flaw was found in the Linux kernel's netfilter BPF Berkeley Packet Filter component. A local attacker could exploit this by initiating a concurrent process to dump hooks via nfnetlinkhooks, which triggers a use-after-free vulnerability. This could lead to system instability or a denial of servi...

CVE-2026-30867

CocoaMQTT is a MQTT 5.0 client library for iOS and macOS written in Swift. Prior to version 2.2.2, a vulnerability exists in the packet parsing logic of CocoaMQTT that allows an attacker or a compromised/malicious MQTT broker to remotely crash the host iOS/macOS/tvOS application. If an attacker...

New Whitepaper: Stealthy BPFDoor Variants are a Needle That Looks Like Hay

Executive Overview Advanced persistent threats APTs are constantly and consistently changing tactics as network defenders plug holes in defenses. Static indicators of compromise IoCs for the BPFDoor have been widely deployed, forcing threat actors to get creative in their use of this particular...

UBUNTU-CVE-2026-23417

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix constant blinding for PROBEMEM32 stores BPFST | BPFPROBEMEM32 immediate stores are not handled by bpfjitblindinsn, allowing user-controlled 32-bit immediates to survive unblinded into JIT-compiled native code when...

CVE-2026-23417

CVE-2026-23417 affects the Linux kernel BPF component where PROBE_MEM32 immediate stores (BPF_ST|BPF_PROBE_MEM32) were not blinded by the JIT constant-blinding path. The root cause is that convert_ctx_accesses() rewrites BPF_ST|BPF_MEM to BPF_ST|BPF_PROBE_MEM32 during verification, but the blindi...

CVE-2026-23412

In the Linux kernel, the following vulnerability has been resolved: netfilter: bpf: defer hook memory release until rcu readers are done Yiming Qian reports UaF when concurrent process is dumping hooks via nfnetlinkhooks: BUG: KASAN: slab-use-after-free in nfnlhookdumpone.isra.0+0xe71/0x10f0 Read...

CVE-2024-53828
