SUSE CVE-2026-52985
In the Linux kernel, the following vulnerability has been resolved: netdevsim: zero initialize struct iphdr in dummy skbuff Syzbot reports a KMSAN uninit-value originating from nsimdevtrapskbbuild, with the allocation also being performed in the same function. Fix this by calling skbputzero inste...
CVE-2026-52985
A flaw was found in the Linux kernel's netdevsim module. An uninitialized memory vulnerability exists in the handling of struct iphdr within a dummy skbuff due to the use of skbput instead of skbputzero. This could lead to unpredictable system behavior, including crashes Denial of Service, or...
CVE-2026-53074
A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Specifically, the bpfprogtestrunskb function, responsible for testing BPF programs with network packets, did not properly validate the length of IPv4 and IPv6 inputs. This could allow the kernel to attempt to access...
CVE-2026-53228
In the Linux kernel, the following vulnerability has been resolved: ipv6: sit: reload inner IPv6 header after GSO offloads ipip6tunnelxmit caches the inner IPv6 header pointer at function entry and continues using it after iptunnelhandleoffloads. For GSO skbs, iptunnelhandleoffloads calls...

CVE-2026-53074 bpf: reject short IPv4/IPv6 inputs in bpf_prog_test_run_skb
In the Linux kernel, the following vulnerability has been resolved: bpf: reject short IPv4/IPv6 inputs in bpfprogtestrunskb bpfprogtestrunskb calls ethtypetrans first and then uses skb-protocol to initialize sk family and address fields for the test run. For IPv4 and IPv6 packets, it may access...
CVE-2026-52985
CVE-2026-52985 concerns the Linux kernel in the netdevsim feature, where the IP header in a dummy skb was not zero-initialized in nsim_dev_trap_skb_build. The issue arises from using skb_put instead of skb_put_zero, leading to uninitialized values in the IP header and potential memory/safety impl...

CVE-2026-45364
Better Auth is an authentication and authorization library for TypeScript. Prior to 1.4.17 and 1.5.0-beta.9, Better Auth's HTTP rate limiter keyed each request by the exact textual IP address it received in x-forwarded-for or the configured IP-bearing header. IPv6 clients controlling a typical /6...

CVE-2026-45850
CVE-2026-45850 pertains to the Linux kernel vulnerability where protocol checksum validation for IPv6 could fail if there are extension headers before the IPv6 header. The confirmed fix uses iph->len as the offset to skip extension headers when performing checksum validation. Technical details...
Astra Linux – Vulnerability in mod-wsgi
A vulnerability was discovered in modwsgi. The X-Client-IP header is not removed from a request sent from a trusted proxy, allowing an attacker to pass the X-Client-IP header to the target WSGI application. The condition necessary to remove the X-Client-IP header is missing...
CVE-2026-43634
CVE-2026-43634 affects HestiaCP versions 1.2.0–1.9.4. The vulnerability is an IP spoofing flaw: unauthenticated attackers can send arbitrary IPs via the CF-Connecting-IP header, bypassing authentication controls and Cloudflare network verification. This can defeat fail2ban brute-force protections...
User Impersonation
Overview Affected versions of this package are vulnerable to User Impersonation due to the reliance on client-supplied IP address headers such as X-Forwarded-For, X-Real-IP, and True-Client-IP. An attacker can circumvent per-IP rate limiting by supplying arbitrary values in these headers, causing...
