CVE-2026-40528 (GCVE-0-2026-40528)

Vulnerability from nvd – Published: 2026-05-29 13:38 – Updated: 2026-07-14 20:00 X_Open Source

Title

OpenSC < 0.27.0 Buffer Overrun in do_key_value() via profile.c

Summary

OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.

CVE-2025-66038 (GCVE-0-2025-66038)

Vulnerability from nvd – Published: 2026-03-30 17:03 – Updated: 2026-04-01 18:15

Title

OpenSC: `sc_compacttlv_find_tag` can return out-of-bounds pointers

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sc_compacttlv_find_tag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag (high nibble) and value length (low nibble). With a 1-byte buffer {0x0A}, the encoded element claims tag=0 and length=10 but no value bytes follow. Calling sc_compacttlv_find_tag with search tag 0x00 returns a pointer equal to buf+1 and outlen=10 without verifying that the claimed value length fits within the remaining buffer. In cases where the sc_compacttlv_find_tag is provided untrusted data (such as being read from cards/files), attackers may be able to influence it to return out-of-bounds pointers leading to downstream memory corruption when subsequent code tries to dereference the pointer. This issue has been patched in version 0.27.0.

Severity

3.9 (Low)

CVE-2025-66037 (GCVE-0-2025-66037)

Vulnerability from nvd – Published: 2026-03-30 17:01 – Updated: 2026-03-30 20:14

Title

OpenSC: Out of Bounds vulnerability

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, feeding a crafted input to the fuzz_pkcs15_reader harness causes OpenSC to perform an out-of-bounds heap read in the X.509/SPKI handling path. Specifically, sc_pkcs15_pubkey_from_spki_fields() allocates a zero-length buffer and then reads one byte past the end of that allocation. This issue has been patched in version 0.27.0.

Title

OpenSC: Stack-buffer-overflow WRITE in GET RESPONSE

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, an attacker with physical access to the computer at the time user or administrator uses a token can cause a stack-buffer-overflow write in GET RESPONSE. The attack requires crafted USB device or smart card that would present the system with specially crafted responses to the APDUs. This issue has been patched in version 0.27.0.

CVE-2026-40528 (GCVE-0-2026-40528)

Vulnerability from cvelistv5 – Published: 2026-05-29 13:38 – Updated: 2026-07-14 20:00 X_Open Source

Title

OpenSC < 0.27.0 Buffer Overrun in do_key_value() via profile.c

Summary

OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.

Title

OpenSC < 0.27.0-rc1 Stack Buffer Overflow via piv_process_history() in card-piv.c

Summary

OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than 118 bytes in the Key History Object ASN.1 response.

CVE-2025-66215 (GCVE-0-2025-66215)

Vulnerability from cvelistv5 – Published: 2026-03-30 17:06 – Updated: 2026-03-31 18:53

Title

OpenSC: Stack-buffer-overflow WRITE in card-oberthur

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, an attacker with physical access to the computer at the time user or administrator uses a token can cause a stack-buffer-overflow WRITE in card-oberthur. The attack requires crafted USB device or smart card that would present the system with specially crafted responses to the APDUs. This issue has been patched in version 0.27.0.

Severity

CVE-2025-66038 (GCVE-0-2025-66038)

Vulnerability from cvelistv5 – Published: 2026-03-30 17:03 – Updated: 2026-04-01 18:15

Title

OpenSC: `sc_compacttlv_find_tag` can return out-of-bounds pointers

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sc_compacttlv_find_tag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag (high nibble) and value length (low nibble). With a 1-byte buffer {0x0A}, the encoded element claims tag=0 and length=10 but no value bytes follow. Calling sc_compacttlv_find_tag with search tag 0x00 returns a pointer equal to buf+1 and outlen=10 without verifying that the claimed value length fits within the remaining buffer. In cases where the sc_compacttlv_find_tag is provided untrusted data (such as being read from cards/files), attackers may be able to influence it to return out-of-bounds pointers leading to downstream memory corruption when subsequent code tries to dereference the pointer. This issue has been patched in version 0.27.0.

Severity

CVE-2025-66037 (GCVE-0-2025-66037)

Vulnerability from cvelistv5 – Published: 2026-03-30 17:01 – Updated: 2026-03-30 20:14

Title

OpenSC: Out of Bounds vulnerability

Summary

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, feeding a crafted input to the fuzz_pkcs15_reader harness causes OpenSC to perform an out-of-bounds heap read in the X.509/SPKI handling path. Specifically, sc_pkcs15_pubkey_from_spki_fields() allocates a zero-length buffer and then reads one byte past the end of that allocation. This issue has been patched in version 0.27.0.

Severity

3.9 (Low)
