Copy Fail · CVE-2026-31431 Escalatazione locale dei privilegi sui kernel Linux dalla versione 4.11 fino alle release 6.18 corrette escluse. Il bug risiede nell'interfaccia socket AFALG del kernel—in particolare nel modo in cui authencesn gestisce le liste scatter-gather durante la decrittazione...

CVE-2026-74678

A flaw was found in the Linux kernel's ax88179178a USB network driver. When the network interface has scatter-gather SG enabled and a packet linearization operation fails, the system fails to free the associated memory buffer. This oversight leads to a memory leak, which could be exploited by an...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Set the correct AMDGPU sg segment limitation. The driver needs to set the correct maxsegmentsize; otherwise, debugdmamapsg will complain about the over-mapping of the AMDGPU sg length as follows: WARNING: CPU: 6 PID:...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: usb: ChipIdea UDC: Fix for DMA and SG cleanup in epnuke The ChipIdea UDC driver may encounter errors where “not-page-aligned sg buffers” occur when a USB device is reconnected after being disconnected during an active transfer...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: tracing/dma: CapDMAmapsg tracepoint arrays to prevent buffer overflows. The dmamapsg tracepoint can cause a PERF buffer overflow when tracing large scatter-gather lists. With devices like virtio-gpu that create large DRM buffers,...

CVE-2026-64464

Consolidated details show CVE-2026-64464 affects the Linux kernel xhci sideband path: xhci_ring_to_sgtable() allocates a temporary pages array used to build an sg_table via sg_alloc_table_from_pages(). On success, the temporary array isn’t freed, causing a leak each time a sideband client uses an...

CVE-2026-64269

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-srv: Bound RDMA-Write length to chunk size in rdmawritesg When the server answers an RTRS READ, rdmawritesg builds the source scatter/gather entry for the IBWRRDMAWRITE that returns data to the peer. Its length is taken...

CVE-2026-64019

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express PCI Peripheral Component Interconnect driver. This vulnerability occurs due to a leak in the Direct Memory Access DMA mapping during data setup operations. Specifically, the system fails to properly unmap DMA resources when...
