CVE-2026-64576

The CVE-2026-64576 issue affects the Linux kernel’s nexthop resolution path (nh_res_bucket_migrate in net/ipv4/nexthop.c), where an uninitialized netlink_ext_ack could be used when allocation fails, leading to a kernel panic. The root cause is the use of an uninitialized extack, which may derefer...

CVE-2026-64465

A flaw was found in the Linux kernel's USB xHCI eXtensible Host Controller Interface driver. When a USB device with active stream endpoints is disconnected, the system attempts to free stream resources while holding a lock with interrupts disabled. This can lead to a situation where a function th...

CVE-2026-64458

A flaw was found in the Linux kernel's Data Access MONitor DAMON subsystem. A local user with write permissions to the system file system sysfs can exploit this vulnerability by configuring extreme zero or excessively high monitoring intervals. This improper handling of interval values can lead t...

CVE-2026-64542

A flaw was found in the Linux kernel's IPv6 Neighbor Discovery NDISC component. An unprivileged user, operating within a network namespace, can trigger a null pointer dereference in the acceptuntrackedna function. This occurs due to a race condition where the inet6dev structure is re-fetched...

CVE-2026-64210

A flaw was found in the Linux kernel's mlx5e driver, which manages Mellanox network adapters. This vulnerability occurs during network processing when CPU core assignments change, leading to a race condition where critical data structures ICOSQ - Interrupt Coalescing Send Queue can be updated...

CVE-2026-64228

A flaw was found in the Linux kernel's ethtool PHY Physical Layer driver. A local attacker can trigger a null pointer dereference by unbinding a PHY driver via sysfs while the device is still attached. This can lead to a kernel crash, resulting in a denial of service...
