Potential buffer overflow vulnerability in the Zephyr CAN bus subsystem
Unchecked user input length in /subsys/net/l2/wifi/wifi_shell.c can cause buffer overflows.
A remote, unauthenticated attacker can trigger memory corruption in Zephyr's HTTP server WebSocket upgrade path by sending a crafted Sec-WebSocket-Key header. The HTTP/1 header parser copies the header into a fixed-size buffer using a bounded copy that does not guarantee NUL termination when the input length reaches the buffer size. During upgrade handling the buffer is copied to a local stack buffer and passed to strlen(); if no NUL exists in-bounds, strlen() reads beyond the stack buffer and subsequent concatenation with the WebSocket magic string can write out of bounds. This leads to out-of-bounds read and write on stack memory, resulting in crash (denial of service) and potentially code execution. The path is reachable when CONFIG_HTTP_SERVER_WEBSOCKET is enabled.
Possible read out of bounds in dns read. Zephyr versions >= 1.14.2, >= 2.3.0 contain Out-of-bounds Read (CWE-125). For more information, see https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-mm57-9hqw-qh44

Signed to unsigned conversion esp32_ipm_send
Inconsistent handling of error cases in bluetooth hci may lead to a double free condition of a network buffer.
dns_unpack_name() caches the buffer tailroom once and reuses it while appending DNS labels. As the buffer grows, the cached size becomes incorrect, and the final null terminator can be written past the buffer. With assertions disabled (default), a malicious DNS response can trigger an out-of-bounds write when CONFIG_DNS_RESOLVER is enabled.
Potential buffer overflows in the Bluetooth subsystem due to asserts being disabled in /subsys/bluetooth/host/hci_core.c
