CVE-2024-11263 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 9.3 CRITICAL
When the Global Pointer (GP) relative addressing is enabled (CONFIG_RISCV_GP=y), the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols.
CVE-2024-10395 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.6 HIGH
No proper validation of the length of user input in http_server_get_content_type_from_extension.
CVE-2023-7060 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.6 HIGH
Zephyr OS IP packet handling does not properly drop IP packets arriving on an external interface with a source address equal to 127.0.01 or the destination address.
CVE-2023-6881 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.3 HIGH
Possible buffer overflow in is_mount_point
