CVE-2026-31680

A flaw was found in the Linux kernel. A local user can exploit a race condition in the IPv6 flow label handling, specifically during the teardown of exclusive flow label options. This can lead to a use-after-free vulnerability when a concurrent reader accesses freed option state, triggering a...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the premature release of exclusive options in the ip6flowlabel when the reference count reaches...

SUSE CVE-2005-3806

The IPv6 flow label handling code ip6flowlabel.c in Linux kernels 2.4 up to 2.4.32 and 2.6 before 2.6.14 modifies the wrong variable in certain circumstances, which allows local users to corrupt kernel memory or cause a denial of service crash by triggering a free of non-allocated memory...

SUSE CVE-2019-18282

The flowdissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash instead of siphash is used. The hashrn...

kernel: The flow_dissector feature allows device tracking

A device tracking vulnerability was found in the flowdissector feature in the Linux kernel. This flaw occurs because the auto flowlabel of the UDP IPv6 packet relies on a 32-bit hashmd value as a secret, and jhash instead of siphash is used. The hashmd value remains the same starting from boot ti...

IPv6 oops triggerable by any user

net/ipv6/tcpipv6.c in Linux kernel 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6flsocklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service OOPS or double free by opening a listening IPv6 socket, attaching a flow label, and connecting to...
