Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the iio adc i-adc161s626 driver's use of stack memory for spiread, which could lead to unsafe DMA...

CVE-2026-31661

The CVE-2026-31661 issue affects the Linux kernel brcmsmac Wi‑Fi driver where dma_free_coherent() may free a size different from what dma_alloc_consistent() allocated (size may change for alignment). The fix changes the free size to the allocation size. Descriptions across multiple advisories (NV...

CVE-2026-31658

CVE-2026-31658 affects the Linux kernel net: altera-tse driver. The root cause is a memory leak: when dma_map_single() fails in tse_start_xmit(), the code returns NETDEV_TX_OK without freeing the skb, causing the skb to be leaked on every DMA mapping failure. The provided patches add dev_kfree_sk...
