CVE-2026-29004: BusyBox before commit 42202bf contains a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler in networking/udhcp/d6_dhcpc.c that allows network-adjacent attackers to trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS option. Attackers can exploit incorrect heap buffer allocation calculations in the option_to_env() function to cause denial of service or achieve arbitrary code execution on embedded systems without heap hardening.

8 issues postponed or untriaged:

CVE-2021-42383: (postponed; to be fixed through a stable update) A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the evaluate function
CVE-2023-39810: (postponed; to be fixed through a stable update) An issue in the CPIO command of Busybox v1.33.2 allows attackers to execute a directory traversal.
CVE-2023-42366: (postponed; to be fixed through a stable update) A heap-buffer-overflow was discovered in BusyBox v.1.36.1 in the next_token function at awk.c:1159.
CVE-2024-58251: (postponed; to be fixed through a stable update) In netstat in BusyBox through 1.37.0, local users can launch of network application with an argv[0] containing an ANSI terminal escape sequence, leading to a denial of service (terminal locked up) when netstat is used by a victim.
CVE-2025-46394: (postponed; to be fixed through a stable update) In tar in BusyBox through 1.37.0, a TAR archive can have filenames hidden from a listing through the use of terminal escape sequences.
CVE-2025-60876: (postponed; to be fixed through a stable update) BusyBox wget thru 1.3.7 accepted raw CR (0x0D)/LF (0x0A) and other C0 control bytes in the HTTP request-target (path/query), allowing the request line to be split and attacker-controlled headers to be injected. To preserve the HTTP/1.1 request-line shape METHOD SP request-target SP HTTP/1.1, a raw space (0x20) in the request-target must also be rejected (clients should use %20).
CVE-2026-26157: (postponed; to be fixed through a stable update) A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files.
CVE-2026-26158: (postponed; to be fixed through a stable update) A flaw was found in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by crafting a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead to privilege escalation, enabling an attacker to gain unauthorized access to critical system files.

1 ignored issue:

CVE-2023-42363: A use-after-free vulnerability was discovered in xasprintf function in xfuncs_printf.c:344 in BusyBox v.1.36.1.
