CVE-2026-68433

In the Linux kernel, the following vulnerability has been resolved: libceph: bound getversion reply decode to front len handlegetversionreply uses msg-frontalloclen as the decode boundary for MONGETVERSIONREPLY. That is the size of the reused reply buffer, not the number of bytes actually receive...

CVE-2026-68433

CVE-2026-68433 : In the Linux kernel’s libceph handling, handle_get_version_reply() decoded the MON_GET_VERSION_REPLY using the buffer’s front_alloc_len (buffer reuse size) instead of the number of bytes actually received. This allowed a truncated reply to pass ceph_decode_need() and decode a sec...

CBORDecoder reuse can leak shareable values across decode calls

Summary When a CBORDecoder instance is reused across multiple decode operations, values marked with the shareable tag 28 persist in memory and can be accessed by subsequent CBOR messages using the sharedref tag 29. This allows an attacker-controlled message to read data from previously decoded...
