CVE-2026-52739 ZEBRA: Repeated Non-Finalized Shielded Transaction Aborts Zebra Before Duplicate-Nullifier Rejection

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a malicious block producer can terminate zebrad by placing the same shielded transaction in a non-finalized parent block and its child. In zebra-state/src/service/nonfinalizedstate/chain.rs, Chain::push originally inserted the...

CVE-2026-52739

Affected: zebrad up to v4.4.1. Root cause: Chain::push in zebra-state/src/service/non_finalized_state/chain.rs:1608-1628 inserts the transaction hash into tx_loc_by_hash with an assert_eq! before running the duplicate shielded-nullifier guard, so a repeated shielded transaction in a child block t...

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Use sender devcom for MPV master-up After PCIe DPC recovery, mlx5 reloads the affected functions and replays multiport affiliation events. In the reported failure, the first relevant device error was: pcieport...

GO-2026-6115 WITHDRAWN: Multiple denial of service vulnerabilities in rsc.io/pdf and forks

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". The PDF parser in rsc.io/pdf and its downstream forks github.com/ledongthuc/pdf and github.com/dslipak/pdf contains multiple defects when parsing untrusted input: - Unchecked /Size, /Index,...

GO-2026-6171 WITHDRAWN: Malformed RowDescription and DataRow messages cause panics in github.com/lib/pq

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". github.com/lib/pq decodes attacker-controlled RowDescription and DataRow payloads without validating their structural relationship or encoded value widths required by binary decoders. A...

GO-2026-6163 Panic on malformed XOR-MAPPED-ADDRESS attribute in github.com/pion/stun/v3

In github.com/pion/stun/v3 before 3.1.5, XORMappedAddress.GetFromAs reads the address family header from an XOR-MAPPED-ADDRESS attribute before validating the attribute length. Parsing a malformed STUN message carrying a zero-length XOR-MAPPED-ADDRESS attribute from a tightly sized buffer causes ...

GO-2026-6237 Denial of service via malformed IPv4 packet in github.com/insomniacslk/dhcp

In github.com/insomniacslk/dhcp/dhcpv4/nclient4, BroadcastRawUDPConn.ReadFrom does not validate that the IPv4 payload length is sufficient to hold a UDP header before calculating the DHCP payload length. A frame with an IPv4 total-length field specifying fewer than eight payload bytes results in ...

GO-2026-6170 WITHDRAWN: Malformed backend frame length causes panic in github.com/lib/pq

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". github.com/lib/pq trusts the unsigned 32-bit length in every PostgreSQL backend frame and subtracts four without first checking that the wire length is at least four. A backend frame whose...

CVE-2026-72206

A flaw was found in the Linux kernel's NTFS filesystem driver. Insufficient validation of index block headers within INDX blocks could allow a local attacker to craft a malicious NTFS filesystem image. When this image is processed by the kernel, it could lead to a kernel panic due to an...

CVE-2026-72191

A flaw was found in the Linux kernel's ntfs3 driver. A local attacker can exploit this vulnerability by mounting a specially crafted NTFS filesystem image. This can lead to an integer underflow during a memory copy operation, resulting in an out-of-bounds kernel write. Successful exploitation...

CVE-2026-72162

A flaw was found in ocfs2, a component of the Linux kernel. On-disk corruption of an inode's embedded extent list can lead to an array-index-out-of-bounds error. This occurs when the lnextfreerec value is zero or exceeds lcount during a write operation to the affected file. A local attacker with...

CVE-2026-72150

A flaw was found in the Linux kernel's sunrpc component. The xprtcreateargs structure is allocated on the stack without initialization in rpcsysfsxprtswitchaddxprtstore. This can lead to critical fields containing uninitialized stack garbage. Exploiting this vulnerability can result in a kernel...

CVE-2026-52731: Uncaught Exception

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an attacker authenticated to an enabled Zebra RPC endpoint can terminate zebrad by supplying a getblocktemplate LongPollId containing multi-byte UTF-8 characters. In zebra-rpc/src/methods/types/longpoll.rs, LongPollId::fromstr...

CVE-2026-52738: Uncaught Exception

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a consensus-valid block containing a long chain of transparent self-spends to one address can permanently halt Zebra nodes.
