Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: Synchronization of RX data at the hardware packet offset. The mvpp2 program modifies the RX queue packet offset, causing the hardware to write received data at dmaaddr + MVPP2SKBHEADROOM. The current CPU synchronizati...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hwmon: nzxt-smart2 DMA-aligned output buffer Sashiko reports that when sendoutputreport calls hidhwoutputreport, the underlying USB HID core calls usbinterruptmsg, which directly maps this buffer for DMA operations. When the DMA...

CVE-2026-74551

In the Linux kernel, the following vulnerability has been resolved: hwmon: nzxt-smart2 DMA-align output buffer Sashiko reports: When sendoutputreport calls hidhwoutputreport, the underlying USB HID core calls usbinterruptmsg which maps this buffer directly for DMA. When the DMA mapping flushes or...

CVE-2026-74551

CVE-2026-74551 affects the Linux kernel hwmon path for nzxt-smart2. The issue arises when send_output_report() triggers USB HID DMA mapping via hid_hw_output_report(), which maps the output buffer for DMA using usb_interrupt_msg(). On non-coherent CPUs (e.g., ARM/MIPS), flushing/invalidating the ...

CVE-2026-68330

In the Linux kernel, the following vulnerability has been resolved: net: airoha: Fix DMA direction for NPU mailbox buffer airohanpusendmsg always maps the mailbox buffer with DMATODEVICE, but some callers expect the NPU to write response data back into the same buffer: - airohanpuwlanmsgget...

EUVD-2026-55431

In the Linux kernel, the following vulnerability has been resolved: net: airoha: Fix DMA direction for NPU mailbox buffer airohanpusendmsg always maps the mailbox buffer with DMATODEVICE, but some callers expect the NPU to write response data back into the same buffer: - airohanpuwlanmsgget...

CVE-2026-68330

CVE-2026-68330 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...

SUSE CVE-2026-53040

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate bgbits during freefrag scan BUG A crafted filesystem can trigger an out-of-bounds bitmap walk when OCFS2IOCINFO is issued with OCFS2INFOFLNONCOHERENT. BUG: KASAN: use-after-free in instrumentatomicread...

CVE-2026-53040

A flaw was found in the Oracle Cluster File System Release 2 OCFS2 in the Linux kernel. A local attacker with the ability to craft a malicious OCFS2 filesystem could trigger a use-after-free vulnerability. This occurs when the OCFS2IOCINFO ioctl is issued with the OCFS2INFOFLNONCOHERENT flag,...

SUSE CVE-2026-53217

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: sync RX data at the hardware packet offset mvpp2 programs the RX queue packet offset, so hardware writes received data at dmaaddr + MVPP2SKBHEADROOM. The current CPU sync starts at dmaaddr and only covers rxbytes +...

CVE-2026-53217

A flaw was found in the Linux kernel's mvpp2 network driver. This issue occurs because the driver incorrectly synchronizes received RX data at the hardware packet offset. On systems with non-coherent Direct Memory Access DMA, this can lead to the Central Processing Unit CPU reading stale cache...

CVE-2026-53217

The CVE-2026-53217 issue affects the Linux kernel MVPP2 driver: RX data was synchronized at the hardware packet offset, leaving end-of-frame data possibly stale on non‑coherent DMA. Root cause is incorrect DMA sync range (starting at dma_addr and not covering the actual written packet tail). The ...
