GHSA-P86G-XRR2-PF7C
Vulnerability from github – Published: 2026-06-19 20:46 – Updated: 2026-06-19 20:46Impact
An unauthenticated remote attacker can pin one server thread‑pool worker at 100 % CPU per connection. With a few connections, the CPU usage can be exhausted.
Preconditions
An attacker being able to reach a service which is exposing an endpoint using one of NetTcpBinding, NetNamedPipeBinding, or UnixDomainSocketBinding.
Patches
Fixed in CoreWCF v1.8.1 and v1.9.1
Workarounds
None

The problem is that the inode contains an xattr entry with ea_inum of 15 when cleaning up an orphan inode <15>. When evict inode <15>, the reference counting of the corresponding EA inode is decreased. When EA inode <15> is found by find_inode_fast() in __ext4_iget(), it is found that the EA inode holds the I_FREEING flag and waits for the EA inode to complete deletion. As a result, when inode <15> is being deleted, we wait for inode <15> to complete the deletion, resulting in an infinite loop and triggering Hung Task. To solve this problem, we only need to check whether the ino of EA inode and parent is the same before getting EA inode.

GHSA-PGGP-6C3X-2XMX
Vulnerability from github – Published: 2026-05-06 20:53 – Updated: 2026-05-13 16:41Summary
Snappier.SnappyStream enters an uncatchable infinite loop when decompressing a malformed framed-format Snappy stream as small as 15 bytes.
Details
The hang manifests as a userspace busy loop with SnappyStreamDecompressor.Decompress repeatedly calling Crc32CAlgorithm.Append. The exact non-terminating loop in or above Decompress has not been traced further.
PoC
using System.IO.Compression;
using Snappier;
byte[] data = { 0x00, 0x04, 0x00, 0x00, 0x64, 0x4e, 0x6c, 0x71, 0x79, 0x20, 0x77, 0x6f, 0x72, 0x6c, 0x64 };
using var src = new MemoryStream(data);
using var snap = new SnappyStream(src, CompressionMode.Decompress);
using var dst = new MemoryStream();
snap.CopyTo(dst); // never returns
Impact
A caller using SnappyStream on attacker-controlled bytes can be made to spin forever and burn a thread until the process is killed. try/catch around the stream operation can't recover (no exception is thrown).
