kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...

CVE-2026-58213

NATS Server (nats-server) before versions 2.14.1 and 2.12.9 is vulnerable: an MQTT client can include protocol control characters in subscription filters, which are later forwarded as NATS protocol data to route or leafnode connections. This corrupts the forwarded protocol stream and allows injec...

Impact rfc3161-client 1.0.2 and earlier contain a flaw in their timestamp response signature verification logic. In particular, it performs chain verification against the TSR's embedded certificates up to the trusted roots, but fails to verify the TSR's own signature against the timestamping leaf...
