libkcapi: IV reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries

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...

libkcapi: Infinite loop denial of service in libkcapi _kcapi_aio_read_all() due to unhandled io_getevents() timeout return

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 kcapiaioreadall function can enter a non-terminating wait loop. This can lead to a persistent...
