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 +...

PT-2026-52312

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the mvpp2 driver where the CPU synchronization for received data is incorrectly aligned. The driver programs the RX queue packet offset such that hardware writes data ...

SUSE CVE-2026-43202

In the Linux kernel, the following vulnerability has been resolved: fbdev: vt8500lcdfb: fix missing dmafreecoherent fbi-fb.screenbuffer is allocated with dmaalloccoherent but is not freed if the error path is reached...

CVE-2026-43149

A flaw was found in the Linux kernel's fslucchdlc module. The uhdlcmemclean function incorrectly deallocates memory by calling dmafreecoherent twice for buffers that were allocated as a single contiguous block. This improper memory handling may lead to a denial of service DoS or other unpredictab...

CVE-2026-43283

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ecbhf: Fix dmafreecoherent dma handle dmafreecoherent in error path takes priv-rxbuf.alloclen as the dma handle. This would lead to improper unmapping of the buffer. Change the dma handle to priv-rxbuf.allocphys...

CVE-2026-43283

The CVE-2026-43283 issue is in the Linux kernel's ec_bhf Ethernet driver where error-path handling used priv->rx_buf.alloc_len as the DMA handle in dma_free_coherent(), risking improper unmapping and potential memory corruption or DoS. The fix changes the DMA handle to priv->rx_buf.alloc_ph...
