CVE-2023-52580

CVE-2023-52580 affects the Linux kernel net/core ETH_P_1588 flow dissector. When a PTP Ethernet raw frame larger than 256 bytes is followed by 0xff, the nhoff calculation uses hdr->message_length (0xffff) and may override nhoff, causing incorrect header length and a kernel crash. The disclosed...

SUSE CVE-2013-4348

The skbflowdissect function in net/core/flowdissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service infinite loop via a small value in the IHL field of a packet with IPIP encapsulation...

SUSE CVE-2017-13715

The skbflowdissect function in net/core/flowdissector.c in the Linux kernel before 4.3 does not ensure that nproto, ipproto, and thoff are initialized, which allows remote attackers to cause a denial of service system crash or possibly execute arbitrary code via a single crafted MPLS packet...

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...

The vulnerability of the flow_dissector function in Linux operating systems allows a hacker to gain unauthorized access to protected information.

The vulnerability of the flowdissector function in Linux operating systems is related to the use of the hash function jhash instead of siphash. Exploiting this vulnerability can allow a remote attacker to gain unauthorized access to protected information...

Linux kernel information disclosure vulnerability (CNVD-2020-03543)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An information disclosure vulnerability exists in the flowdissector function in Linux kernel versions 4.3 through 5.x fixed in version 5.3.10. The vulnerability stems...

The vulnerability of the skb_flow_dissect function in the flow_dissector.c file of the kernel’s Linux operating system allows a attacker to cause a service failure or execute arbitrary code.

The vulnerability of the skbflowdissect function in the flowdissector.c file of the Linux kernel’s network subsystem is related to insufficient input validation. The function returns a value of true for the keycontrol protocol without setting values for nproto, ipproto, and thoff. Exploiting this...
