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...

CVE-2026-31398

A flaw was found in the Linux kernel's memory management unit MMU. A local user could exploit this vulnerability by manipulating memory operations, leading to incorrect page table entry PTE restoration for lazyfree folios during batch unmapping. This issue can cause memory pages with mixed writab...

CVE-2026-23432

A flaw was found in the Linux kernel's mshv component. A local user could exploit a use-after-free vulnerability by unmapping memory after a specific error path in the mshvmapusermemory function. This can cause a system crash kernel panic due to the system attempting to access freed memory...
