grafana: Grafana Auth Proxy: Unauthorized access due to incorrect IPv6 allow-list default

A flaw in Grafana's Auth Proxy IPv6 allow-list incorrectly defaults to a broad /32 subnet mask instead of a strict /128. This misconfiguration allows remote attackers to bypass access restrictions, potentially leading to unauthorized access and data manipulation...

An update for grafana is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...

CVE-2026-74630

A flaw was found in the Linux kernel's IPv6 subsystem. The in6devget function can incorrectly increment the reference count of an inet6dev object after it has been freed, leading to a use-after-free vulnerability. A local attacker could exploit this to cause memory corruption, potentially resulti...

CVE-2026-74598

A flaw was found in the Linux kernel's IPv6 networking stack. An off-by-one error in the validation of the Route Information option length RFC 4191 allows a remote attacker to craft a Router Advertisement RA packet. This crafted packet can cause the kernel to read up to 8 bytes beyond the intende...

CVE-2026-74597

A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 tunnel error handling. A remote attacker could send a specially crafted IPv6 ICMP Internet Control Message Protocol error packet with a malformed inner destination-options header. This could lead to memory corruption within t...

CVE-2026-74657

A flaw was found in the Linux kernel. The fibnlmsgsize function, which estimates the size for network message buffers, incorrectly calculates the required space for nexthops when IPv4 routes contain an IPv6 gateway. This error can lead to the allocation of an undersized buffer for route...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Reenabling NETIFFIPV6CSUM offloading for BIG TCP packets The problematic commit disabled the hardware offloading of IPv6 packets with extension headers on devices that advertise NETIFFIPV6CSUM. This was based on the definiti...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nexthop: The nh-lock is taken during the f6ilist walk in the replace operation, but it is replaced promptly without holding the nh-lock. In this way, the RTNL-serialized nexthop replace operation occurs without holding the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ipv6: ioam: Fixed the type confusion of dstentry. IOAM uses a dummy dstentry nulldst to indicate that the destination should not be changed after the transformation. This destination is stored in the IOAM lwt state and may be...

CVE-2026-75975

fast-uri is a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not validate the complete IPv6 grammar, so invalid trailing text in an authority can be silently discarded and a malformed attacker-controlled host is turned into a different valid IPv6 destination. For...
