CVE-2026-68397

The CVE-2026-68397 issue affects the Linux kernel net/iucv code: afiucv_hs_rcv() may pass a destination socket to handlers without holding a reference, allowing a concurrent close to free the socket before the handler dereferences it (e.g., sk->sk_data_ready()) because AF_IUCV sockets aren’t R...

CVE-2026-68395

CVE-2026-68395 pertains to the Linux kernel’s SATA DWC 460ex driver. The issue was that sata_dwc_enable_interrupts() was executed before the IRQ handler and related initialization (platform_get_irq(), ata_host_activate()), leaving the SATA controller’s interrupt mask enabled without a registered ...
