Fixes the following vulnerabilities:
- CVE-2025-59391:
A memory disclosure vulnerability exists in libcoap's OSCORE
configuration parser in libcoap before release-4.3.5-patches. An out-
of-bounds read may occur when parsing certain configuration values,
allowing an attacker to infer or read memory beyond string boundaries
in the .rodata section. This could potentially lead to information
disclosure or denial of service.

- CVE-2025-65493:
NULL pointer dereference in src/coap_openssl.c in OISM libcoap 4.3.5
allows remote attackers to cause a denial of service via a crafted
DTLS/TLS connection that triggers BIO_get_data() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65493
- CVE-2025-65494:
NULL pointer dereference in get_san_or_cn_from_cert() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted X.509 certificate that causes
sk_GENERAL_NAME_value() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65494
- CVE-2025-65495:
Integer signedness error in tls_verify_call_back() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted TLS certificate that causes
i2d_X509() to return -1 and be misused as a malloc() size parameter.
https://www.cve.org/CVERecord?id=CVE-2025-65495
- CVE-2025-65496:
NULL pointer dereference in coap_dtls_generate_cookie() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted DTLS handshake that triggers
SSL_get_SSL_CTX() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65496
- CVE-2025-65497:
NULL pointer dereference in coap_dtls_generate_cookie() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted DTLS handshake that triggers
SSL_get_SSL_CTX() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65497
- CVE-2025-65498:
NULL pointer dereference in coap_dtls_generate_cookie() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted DTLS handshake that triggers
SSL_get_SSL_CTX() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65498
- CVE-2025-65499:
Array index error in tls_verify_call_back() in src/coap_openssl.c in
OISM libcoap 4.3.5 allows remote attackers to cause a denial of
service via a crafted DTLS handshake that triggers
SSL_get_ex_data_X509_STORE_CTX_idx() to return -1.
https://www.cve.org/CVERecord?id=CVE-2025-65499
- CVE-2025-65500:
NULL pointer dereference in coap_dtls_generate_cookie() in
src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to
cause a denial of service via a crafted DTLS handshake that triggers
SSL_get_SSL_CTX() to return NULL.
https://www.cve.org/CVERecord?id=CVE-2025-65500
- CVE-2025-65501:
Null pointer dereference in coap_dtls_info_callback() in OISM libcoap
4.3.5 allows remote attackers to cause a denial of service via a DTLS
handshake where SSL_get_app_data() returns NULL.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
