CVE-2026-75584 ION-DTN < 4.2.1-a.1 Denial of Service via canonicalizePayloadBlock() Assertion

ION-DTN before 4.2.1-a.1 contains a denial of service vulnerability that allows unauthenticated remote attackers to crash the ION process by sending a BPv7 bundle with a zero-length payload. The canonicalizePayloadBlock function in bpsecutil.c passes bundle-payload.length to zcoclone without...

CVE-2026-80794

This Linux kernel vulnerability affects the NFC NCI subsystem, specifically the nci_rf_discover_ntf_packet() and nci_rf_intf_activated_ntf_packet() handlers. The root cause is that on-stack notification structs are not zero-initialised before parsing. When a notification reports a zero rf_tech_sp...

CVE-2026-80794 nfc: nci: fix uninit-value in the RF discover/activated NTF handlers

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fix uninit-value in the RF discover/activated NTF handlers ncirfdiscoverntfpacket and ncirfintfactivatedntfpacket each parse a notification into an on-stack struct ncirfdiscoverntf / ncirfintfactivatedntf that is not...

kernel: iomap: fix out-of-bounds bitmap_set() with zero-length range

A flaw was found in the Linux kernel's iomap subsystem. An unsigned subtraction underflow occurs when ifssetrangedirty or ifssetrangeuptodate are called with a zero-length range. This can lead to an out-of-bounds write via bitmapset, potentially allowing a local attacker to cause memory corruptio...

kernel: NFSv4/pNFS: reject zero-length r_addr in nfs4_decode_mp_ds_addr

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...
