kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns

A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...

CVE-2026-63987

A flaw was found in the Linux kernel's ethtool subsystem. The ethnlupdateprofile function, responsible for updating profile settings, does not properly validate user-controlled input when processing Netlink nest lists. This allows a local attacker to cause an out-of-bounds write, potentially...

CVE-2026-63985

A flaw was found in the Linux kernel's ethtool component, specifically within the EEPROM Netlink fallback path. The fallbacksetparams function fails to properly validate the length of data being read from the module's EEPROM, allowing for an out-of-bounds read. Additionally, the eepromfallback...

CVE-2026-63860

A flaw was found in the Linux kernel's RDMA/core component. This vulnerability arises from the improper handling of Netlink Attribute NLA strings, where attributes evaluated as C-strings do not properly check for a null terminator. A local attacker could potentially provide specially crafted inpu...
