CVE-2026-31640

A flaw was found in the Linux kernel's rxrpc component. This vulnerability occurs in the rxrpcpostresponse function, where the system incorrectly compares a newer network packet's data instead of the expected cached response. This error causes the challenge serial number comparison to always be...

CVE-2026-31635

A flaw was found in the Linux kernel's rxrpc component. An inverted length check in the rxgkverifyresponse function allows oversized RESPONSE authenticators to be accepted. This can lead to an impossible length being passed to skbtosgvec, triggering a BUGON condition and resulting in a system...

Traefik: A timing side-channel vulnerability allows for valid username enumeration via BasicAuth middleware

Summary There is a timing side-channel vulnerability in Traefik's BasicAuth middleware that allows an attacker to enumerate valid usernames through response-time differences. The variable intended to hold a constant-time fallback secret always resolves to an empty string, causing the constant-tim...

CVE-2026-35343

The cut utility in uutils coreutils incorrectly handles the -s only-delimited option when a newline character is specified as the delimiter. The implementation fails to verify the onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

CVE-2026-35339

The recursive mode -R of the chmod utility in uutils coreutils incorrectly handles exit codes when processing multiple files. The final return value is determined solely by the success or failure of the last file processed. This allows the command to return an exit code of 0 success even if error...

CVE-2026-41894

SiYuan is an open-source personal knowledge management system. Prior to 3.6.5, the fix for CVE-2026-30869 only added a denylist check IsSensitivePath but did not address the root cause — a redundant url.PathUnescape call in serveExport. An authenticated attacker can use double URL encoding...

CVE-2026-41678

rust-openssl provides OpenSSL bindings for the Rust programming language. From to before 0.10.78, aes::unwrapkey contains an incorrect assertion: it checks that out.len + 8 = in.len - 8, ensuring the output buffer is large enough. Because of the inverted check, the function only accepts buffers a...

CVE-2026-31564

A flaw was found in the Linux kernel, specifically within the Kernel-based Virtual Machine KVM component for LoongArch architecture. An incorrect base address calculation in the kvmeiointcregsaccess function, where a u64 type was not properly converted to a void before adding an offset, could lea...

CVE-2026-41681

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVPDigestFinal always writes EVPMDCTXsizectx to the out buffer. If out is smaller than that, MdCtxRef::digestfinal writes past its end, usually corrupting the stack. This is reachable from sa...

Apache Airflow's asset dependency graph did not restrict nodes by the viewer's DAG read permissions

The asset dependency graph did not restrict nodes by the viewer's DAG read permissions: a user with read access to at least one DAG could browse the asset graph for any other asset in the deployment and learn the existence and names of DAGs and assets outside their authorized scope. Users are...
