GO-2026-5051 Out-of-bounds read and panic in ReadDir in github.com/cloudsoda/go-smb2 and github.com/hirochachacha/go-smb2

ReadDir and ReadDirPlus parse the QUERYDIRECTORY SMB response by advancing through entries using the server-supplied NextEntryOffset field. The pre-fix code does not bound next against the remaining buffer before re-slicing, and the entry decoder IsInvalid check performs length arithmetic in int...

GO-2026-5046 CPU exhaustion in Avro decoder in github.com/iskorotkov/avro/v2 and github.com/hamba/avro/v2

The Avro array and map decoders loop over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 and arm64 targets. A producer can declare a block of up to...

GO-2026-5048 Denial of service via unbounded map allocations in github.com/iskorotkov/avro/v2 and github.com/hamba/avro/v2

The Avro map decoder accepts attacker-controlled block-element counts from the wire format and grows the destination map without enforcing an upper bound. A producer can declare an arbitrarily large map in one block, or chunked across many sub-limit blocks and exhaust process memory until the OOM...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the mapDecoder.Decode and mapDecoderUnmarshaler.Decode methods in codecmap.go, which use the attacker-controlled map block element count both to pre-size the destination map and as...

CVE-2026-64384

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...

CVE-2026-64437

A flaw was found in the ksmbd component of the Linux kernel. This vulnerability allows an authenticated client using the Server Message Block SMB protocol to trigger a use-after-free error. By sending specific close and cancel requests, an attacker can cause the kernel to crash, leading to a deni...

CVE-2026-64509

A flaw was found in the Linux kernel's rust: block module. This vulnerability occurs in the GenDisk cleanup paths, where temporary disk and request queue resources may not be properly released during error handling or after unregistration. This can lead to a resource leak, potentially causing...

CVE-2026-64393

A flaw was found in the Linux kernel's ksmbd component. This vulnerability allows a local attacker to escalate privileges by manipulating Server Message Block SMB2 SETINFO operations. The system incorrectly uses the ksmbd worker's credentials instead of the original user's credentials when...

CVE-2026-64398

A flaw was found in the Linux kernel's ksmbd component. An authenticated Server Message Block SMB client with only FILEWRITEATTRIBUTES permission can bypass a security check in the FSCTLSETZERODATA function. This allows the client to zero out file data, leading to data destruction and a denial of...

CVE-2026-64397

A flaw was found in the Linux kernel's ksmbd kernel Server Message Block daemon component. Concurrent directory query requests using the same file handle can lead to a stack use-after-free vulnerability. This occurs because smb2querydir stores a pointer to stack-allocated data that can be...
