CVE-2020-25600

An issue was discovered in Xen through 4.14.x. Out of bounds event channels are available to 32-bit x86 domains. The so called 2-level event channel model imposes different limits on the number of usable event channels for 32-bit x86 domains vs 64-bit or Arm either bitness ones. 32-bit x86 domain...

CVE-2020-25600

The connected XSA-342 advisory provides concrete details for CVE-2020-25600: Xen 2-level event channel model mismanages the per-guest limit, causing 32-bit x86 domains (including Domain 0) to observe successful allocations that should fail, risking corruption of the shared info structure and enab...

Xen buffer overflow vulnerability (CNVD-2020-53819)

out of bounds event channels available to 32-bit x86 domains

ISSUE DESCRIPTION The so called 2-level event channel model imposes different limits on the number of usable event channels for 32-bit x86 domains vs 64-bit or Arm either bitness ones. 32-bit x86 domains can use only 1023 channels, due to limited space in their shared between guest and Xen...

CVE-2020-0407

In various functions in fscryptice.c and related files in some implementations of f2fs encryption that use encryption hardware which only supports 32-bit IVs Initialization Vectors, 64-bit IVs are used and later are truncated to 32 bits. This may cause IV reuse and thus weakened disk encryption...
