CVE-2026-47859 Unbounded memory allocation in RFC6587SyslogDeserializer (octet-counted framing) — remote DoS

RFC6587SyslogDeserializer, used by the Spring Integration syslog TCP inbound adapter to decode RFC 6587 / RFC 5424 frames, trusts the sender-supplied octet count of an octet-counted frame and allocates a byte array of exactly that size with no upper bound. Spring Integration 7.1.0 Spring...

CVE-2026-56814 Plug: multipart :length limit is not charged for part headers, enabling unbounded temp-file creation (denial of service)

Plug.Parsers.MULTIPART, the multipart request-body parser used to handle file uploads and multipart forms, does not enforce its :length budget against all consumed resources, allowing an unauthenticated remote attacker to cause denial of service. The parser charges the :length limit only for part...

CVE-2026-39979 jq: Out-of-Bounds Read in jv_parse_sized() Error Formatting for Non-NUL-Terminated Counted Buffers

jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jvparsesized API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jvstringfmt, which reads until a NUL terminat...

PT-2026-3079

The SharedPointer::alloc implementation for sync::Arc and rc::Rc in rkyv/src/impls/alloc/rc/atomic.rs and rc.rs does not check if the allocator returns a null pointer on OOM Out of Memory. This null pointer can flow through to SharedPointer::from value, which calls Box::from rawptr with the null...
