Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Initialize freeqp completion before using it. In irdmacreateqp, if ibcopytoudata fails, it will call irdmadestroyqp to clean up. This process will attempt to wait for the completion of freeqp, but freeqp has not yet...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. The issue arises when handling the “PVRDMACMDCREATEMR” command due to improper memory remapping mremap. This flaw allows a malicious guest to crash the QEMU process on the host. The greatest threat posed by this...

Astra Linux – Vulnerability in Chromium

Type confusion in V8 in Google Chrome prior to 101.0.4951.41 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/irdma: Fixed the bug where sleep operations occurred from an invalid context. RoCEv2 QP processing in netdev events caused a kernel split. This issue was fixed by removing the handling of RoCEv2 in...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Ensure that rdmaaddrcancel is executed before issuing more requests. The FSM can enter a loop, allowing rdmaresolveip to be called twice with the same idpriv. Although this cannot occur without going through this proces...

Astra Linux – Vulnerability in Chromium

Before version 123.0.6312.58, using Swiftshader in Google Chrome allowed a remote attacker to perform out-of-bounds memory access through a crafted HTML page. Chromium security severity: Medium...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: A memory leak has been fixed in hnsroceallocmr. When hnsrocemrenable fails in hnsroceallocmr, mrkey is not released. This issue only affects compiled tests...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. This flaw allows a malicious guest driver to allocate and initialize a large number of page tables, which can be used as a ring of descriptors for CQ and async events. This could potentially lead to out-of-bound...

CVE-2026-54874: Asymmetric Resource Consumption (Amplification)

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevention of certain integer underflows My static checker reports the following issue: drivers/infiniband/hw/irdma/ctrl.c:3605 irdmascceqinit Warning: Can subtract underflow for ‘info-dev-hmcfpmmisc.maxceqs’? It seem...

EUVD-2026-60321

COVESA Open1722 through 0.9.2 contains an integer truncation vulnerability in acf-can-listener.c that allows unauthenticated remote attackers to cause the CAN listener to transmit process stack memory onto the CAN bus by sending a rejected UDP datagram with a matching AVTP stream ID. The numcanms...

CVE-2026-71218 Iperf3: unbounded peer-controlled allocation in iperf3 json_read() allows unauthenticated remote memory exhaustion

A flaw was found in iperf3. A remote unauthenticated attacker can exploit a vulnerability in the JSONread function, which accepts a peer-controlled message length and allocates memory without an upper bound. This allows the attacker to trigger excessive memory consumption, leading to a Denial of...

CVE-2026-68419

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent reregmr for non-mem regions When a QP/CQ/SRQ is created, a two step process is used where the buffer is allocated in userspace and explicitly registered with the normal regmr mechanism prior to creating the...

CVE-2026-68419 RDMA/irdma: Prevent rereg_mr for non-mem regions

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent reregmr for non-mem regions When a QP/CQ/SRQ is created, a two step process is used where the buffer is allocated in userspace and explicitly registered with the normal regmr mechanism prior to creating the...

EUVD-2026-55605

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent reregmr for non-mem regions When a QP/CQ/SRQ is created, a two step process is used where the buffer is allocated in userspace and explicitly registered with the normal regmr mechanism prior to creating the...

CVE-2026-68419

The CVE-2026-68419 affects the Linux kernel RDMA/irdma subsystem. When a QP/CQ/SRQ is created, a two-step process allows user-space buffers to be registered with reg_mr via a special ABI flag indicating an invalid mkey. This can enable a user to call rereg_mr on these MR objects and trigger a rea...
