CVE-2026-71225 [MEDIUM] CWE-330 CVE-2026-71225: A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs ( A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application t

CVE-2026-71226 [HIGH] CWE-416 CVE-2026-71226: Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an e Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers.

CVE-2026-71227 [MEDIUM] CWE-835 CVE-2026-71227: A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchrono A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected applicatio
