CVE-2026-31660

The CVE-2026-31660 entry concerns the Linux kernel NFC pn533 driver. The root cause is that pn532_receive_buf() may hand a complete frame to pn533_recv_frame() before allocating a fresh receive buffer; if alloc_skb() fails, the callback returns 0 while bytes have already been consumed, leaving re...

Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a failure in the allocation of the receive buffer in the pn533 driver. This failure may lead to null...

NanoMQ Buffer Overflow Vulnerability (CNVD-2026-16831)

NanoMQ is a lightweight and fast MQTT Broker for IoT edge platforms. A buffer overflow vulnerability exists in NanoMQ versions prior to 0.24.8. The vulnerability stems from the MQTT-over-WebSocket transport failing to properly validate the receive buffer size when processing MQTT packets with...

PT-2026-51976

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the sixpack receive buf function where bytes with TTY error flags are not properly skipped. The function iterates through the flags buffer without advancing the data...

PT-2026-35012

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the NFC PN533 component where the pn532 receive buf function may fail to allocate a fresh receive buffer before consuming bytes. If the alloc skb function fails, the...

CVE-2026-28526

BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller LISTPLAYERAPPLICATIONSETTINGATTRIBUTES and LISTPLAYERAPPLICATIONSETTINGVALUES handlers that allows attackers to read beyond buffer boundaries. A nearby attacker with a paired Bluetooth...

CVE-2026-28526: Out-of-bounds Read

PT-2026-36449

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the NFC pn533 component, the pn532 receive buf function appends incoming bytes to dev-recv skb and only resets the buffer upon recognition of a complete frame by pn532 uart rx is fram...

curl: SMB READ_ANDX DataOffset not validated

Summary: in smbrequeststate case SMBDOWNLOAD curl reads two server-controlled fields from a READANDX response and uses them to decide where in the receive buffer file data starts. c / lib/smb.c / len = Curlread16leconst unsigned char msg + sizeofstruct smbheader + 11; off = Curlread16leconst...

kernel: tcp: fix a signed-integer-overflow bug in tcp_add_backlog()

A flaw was found in the Linux kernel’s TCP implementation in the function tcpaddbacklog. When calculating the maximum acceptable backlog for TCP sockets, the sum of the receive buffer skrcvbuf, the send buffer sksndbuf, and a fixed constant may exceed the maximum value of a signed integer due to...

Linux TTY Console Driver Heap Buffer Overflow DoS

The vulnerability of the gsmldreceivebuf function in the drivers/tty/ngsm.c module of the TTY console driver for the Linux operating system is related to the assignment of the NULL pointer. Exploiting this vulnerability could allow a remote attacker to cause a service failure...
