curl: CVE-2026-11352: QUIC zero-length UDP datagrams busy-loop

Summary: curl's QUIC UDP receive helper ignores zero-length UDP datagrams before counting them against the per-call packet budget. On Linux, recvmmsgpackets loops while pkts maxpkts, but if!mmsgi.msglen continue; runs before pkts is incremented. The recvmsgpackets backend has the same no-progress...

curl: OpenSSL TLS 1.2 session resumption accepts expired server certificates in libcurl

Summary curl's OpenSSL backend can accept a new TLS 1.2 HTTPS connection after the server certificate has expired if the connection resumes a previously cached TLS session. A full handshake made at the same time with the same certificate fails with CURLEPEERFAILEDVERIFICATION, but the resumed...

curl: DNS domain search list followed for extant domain missing A or AAAA records

Summary: Curl calls getaddrinfo to resolve a domain's addresses, however glibc will continue though the domain search list to find data even if it gets a NODATA response. When using AFUNSPEC in the aihints, this search will stop at the first domain with either an A or AAAA record, however when...

curl: PRE_PROXY change leaks stale Proxy Digest state across proxy-chain boundary

Summary After a Digest-authenticated HTTP proxy transfer, changing only CURLOPTPREPROXY on the same libcurl easy handle does not clear stale proxy Digest/auth state. If the new SOCKS pre-proxy resolves the same HTTP proxy hostname to a different proxy endpoint, the second proxy receives a...

curl: libcurl 8.20.0 ignores HTTP Digest domain protection space and preemptively leaks Digest auth outside the declared scope

Summary: libcurl 8.20.0 ignores the server-declared HTTP Digest domain protection space for origin authentication and reuses stored Digest state too broadly on the same easy handle. After a successful Digest-authenticated request, a later request on the same easy handle can receive a preemptive...

curl: heap-use-after-free in state.referer when CURLOPT_REFERER replaced or cleared after perform

Calling curleasysetoptcurl, CURLOPTREFERER, ... to replace or clear a previously-set referer after curleasyperform frees the old string via Curlsetstropt lib/setopt.c:87 but leaves data-state.referer.ptr pointing at the freed heap region. curleasygetinfoCURLINFOREFERER and curleasyduphandle then...

curl: curl/libcurl 8.20.0 NOPROXY bypass via uppercase-hex IPv4 aliases leaks off-proxy Basic credentials to the configured proxy

Summary: curl/libcurl 8.20.0 fails to enforce CURLOPTNOPROXY, --noproxy, and NOPROXY consistently for uppercase-hex IPv4 aliases such as 0X7f.1 on glibc-based systems that accept these legacy numeric IPv4 forms. When a canonical IP literal is excluded from proxying, curl sends the canonical form...

SUSE CVE-2026-49129

NeuroLog: Reasoning You Can Audit -- Neuro-Symbolic Vulnerability Discovery Via LLM Facts, Datalog, and SMT

Vulnerability discovery on C/C++ source asks the analyst to choose between heavyweight static analysers, which need a working build before a single query runs, and free-form LLMs, which read source readily but invent details and lose track of cross-function dataflow on real codebases. We present...
