CVE-2026-80801

CVE-2026-80801 affects the Linux kernel's NFC microread driver. The function microread_target_discovered() parses target discovery payloads from skb->data according to the HCI gate, but fixed field offsets and UID copies were validated only against the destination nfc_target buffers rather tha...

CVE-2026-80800 nfc: llcp: bound the connect_sn TLV walk to the skb

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: bound the connectsn TLV walk to the skb Commit 27256cdb290e "nfc: llcp: bound SNL TLV parsing to the skb and add length checks" fixed the unbounded TLV walk in nfcllcprecvsnl, and commit d8bd2dedbde5 "nfc: llcp: fix OO...

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...

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-2026-80789

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: bound SGL data length before allocating command buffers nvmettcpmapdata reads the host-controlled 32-bit sgl-length and, for the in-capsule offset descriptor type 0x01, checks it against port-inlinedatasize before use...

CVE-2026-80789

In the Linux kernel nvmet-tcp component (NVMe/TCP target), a host-controlled 32-bit sgl->length field is only validated for in-capsule SGL descriptors. Non-inline transport SGL data-block descriptors—those used for out-of-capsule writes—skip the check entirely, causing an unbounded sgl_alloc()...

CVE-2026-80760

CVE-2026-80760 affects the Linux kernel Bluetooth MGMT subsystem. The function mgmt_hci_cmd_sync() validates that the message length matches params_len but fails to enforce an upper bound. Since params_len is a 16-bit value while the HCI command header plen field is 8-bit (max 255), a value of 25...

CVE-2026-80759

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciaml: validate firmware segment lengths amldownloadfirmware reads two lengths from the firmware header and uses them to build pointers before checking that the header and segment data are present. A truncated or...

CVE-2026-81666 Corosync: corosync: integer overflow in check_memb_commit_token_sanity may bypass message length validation on 32-bit systems

An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an...

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...
