CVE-2026-74525

CVE-2026-74525 affects the Linux kernel net sxgbe driver. When RX descriptor ring allocation fails, init_dma_desc_rings() frees partial RX rings but leaks TX rings allocated earlier. The fix rearranges error labels to clean up TX rings on RX failure. Affected component: net/sxgbe RX/TX ring initi...

CVE-2026-74478

CVE-2026-74478 affects the Linux kernel, specifically the vector_mmsg_rx() path. When a packet is discarded because verify_header() fails, the code previously continued without advancing the slot, leaving a freed skb in the vector and causing a use-after-free in the RX path. The issue can be trig...
