CVE-2026-28364 (GCVE-0-2026-28364)
Vulnerability from cvelistv5 – Published: 2026-02-27 03:54 – Updated: 2026-02-27 15:49
VLAI
Summary
In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization (runtime/intern.c) enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock() function, which performs unbounded memcpy() operations using attacker-controlled lengths from crafted Marshal data.
Severity

Title
libgphoto2 has an OOB Read in ptp_unpack_EOS_FocusInfoEx
Summary
libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, an out of bound read in ptp_unpack_EOS_FocusInfoEx could be used to crash libgphoto2 when processing input from untrusted USB devices. Commit c385b34af260595dfbb5f9329526be5158985987 contains a patch. No known workarounds are available.

Title
rust-openssl: Unchecked callback-returned length in PSK and cookie generate trampolines can cause OpenSSL to leak adjacent memory to the network peer
Summary
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.24 to before 0.10.78, the FFI trampolines behind SslContextBuilder::set_psk_client_callback, set_psk_server_callback, set_cookie_generate_cb, and set_stateless_cookie_generate_cb forwarded the user closure's returned usize directly to OpenSSL without checking it against the &mut [u8] that was handed to the closure. This can lead to buffer overflows and other unintended consequences. This vulnerability is fixed in 0.10.78.

CVE-2026-5772 (GCVE-0-2026-5772)

Title
MatchDomainName 1-Byte Stack Buffer Over-Read in Hostname Validation
Summary
A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash.

Title
Buffer overread in ns_printrrf with corrupted RDATA field
Summary
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory.
These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.

Title
PostgreSQL pg_restore_attribute_stats accepts values that cause query planning to read past end of stats array
Summary
Buffer over-read in PostgreSQL function pg_restore_attribute_stats() accepts array values of unmatched length, which causes query planning to read past end of one array. This allows a table maintainer to infer memory values past that array end. Within major version 18, minor versions before PostgreSQL 18.4 are affected. Versions before PostgreSQL 18 are unaffected.
