PYSEC-2026-2615 Magic Wormhole: "wormhole receive" allows arbitrary local file overwrite

Impact What kind of vulnerability is it? Who is impacted? Receiving a file wormhole receive from a malicious party could result in overwriting critical local files, including /.ssh/authorizedkeys and .bashrc. This could be used to compromise the receiver's computer. Only the sender of the file th...

CVE-2026-10665

CVE-2026-10665 concerns Zephyr’s WireGuard implementation (subsys/net/lib/wireguard). The flaw: wg_process_data_message() linearizes an inbound payload into a fixed pool buffer, passing the attacker-controlled data_len as both the destination capacity and copy length to net_buf_linearize, ignorin...

CVE-2026-10665 Heap buffer overflow on WireGuard receive path via unbounded incoming packet length

In Zephyr's WireGuard subsystem subsys/net/lib/wireguard, wgprocessdatamessage in wgcrypto.c linearizes an inbound transport-data payload into a fixed pool buffer of CONFIGWIREGUARDBUFLEN bytes before decryption. The call netbuflinearizebuf-data, datalen, pkt-buffer, ..., datalen passed the...

CVE-2026-29008 U-Boot 2026.04-rc3 Integer Underflow DoS via tcp_rx_state_machine()

U-Boot through 2026.04-rc3 contains an integer underflow vulnerability in the tcprxstatemachine function net/tcp.c that allows a network-adjacent attacker to crash the bootloader by sending a malformed TCP SYN+ACK packet with a manipulated data offset field causing payloadlen to become negative...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

389-ds-base: 389-ds-base: Heap buffer overflow in sasl_io_recv() via padded SASL UNBIND

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. After a successful SASL bind with integrity protection SSF 0, an authenticated attacker can send a specially crafted oversized LDAP UNBIND packet that is copied into a 512-byte heap receive buffer...

PT-2026-56475

Name of the Vulnerable Software and Affected Versions U-Boot versions prior to 2026.04-rc3 Description An integer underflow exists in the tcp rx state machine function within net/tcp.c. A network-adjacent attacker can trigger this by sending a malformed TCP SYN+ACK packet with a manipulated data...

The vulnerability of the iavf_config_rss_reg() function in the driver/net/ethernet/intel/iavf/iavf_main.c file of the Intel Ethernet network adapter driver for the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the iavfconfigrssreg function in the driver/net/ethernet/intel/iavf/iavfmain.c file of the Intel Ethernet network adapter driver for the Linux operating system is related to reading beyond the buffer boundaries. Exploiting this vulnerability could allow an attacker to...

PT-2026-56474

Name of the Vulnerable Software and Affected Versions U-Boot versions prior to 2026.04-rc4 Description An out-of-bounds read occurs in the tcp rx state machine function net/tcp.c when CONFIG PROT TCP is enabled. A remote attacker can read beyond TCP segment boundaries by sending a malicious packe...

kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...
