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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the dmaalloccoherent function in the vt8500lcdfb driver. The memory allocated by this function is...
