Lychee 代码问题漏洞

Lychee is a beautiful and easy-to-use photo management system developed by The Lychee Organisation. It is used for managing and sharing photos. Versions of Lychee prior to 7.5.1 had code vulnerabilities; these vulnerabilities stemmed from incomplete IP verification checks, which failed to prevent...

PT-2026-28492

Name of the Vulnerable Software and Affected Versions Lychee versions prior to 7.5.1 Description Lychee is a free, open-source photo-management tool. A flaw exists in the IP validation check within the patch for an SSRF issue related to Photo::fromUrl. This incomplete check fails to block loopbac...

CVE-2026-23353

A flaw was found in the Linux kernel's ice network driver. When a local user performs an ethtool offline loopback test, the system can experience a kernel null pointer dereference. This occurs because the libeth library for the receive ring is not properly initialized. Successful exploitation of...

SUSE CVE-2026-23300

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: fix panic when IPv4 route references loopback IPv6 nexthop When a standalone IPv6 nexthop object is created with a loopback device e.g., "ip -6 nexthop add id 100 dev lo", fib6nhinit misclassifies it as a reject route...

SUSE CVE-2026-23304

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix NULL pointer deref in ip6rtgetdevrcu l3mdevmasterdevrcu can return NULL when the slave device is being un-slaved from a VRF. All other callers deal with this, but we lost the fallback to loopback in ip6rtpcpualloc -...

CVE-2026-23300

A flaw was found in the Linux kernel's IPv6 networking stack. When a standalone IPv6 nexthop object is created with a loopback device, it is misclassified as a reject route, leading to an unallocated pointer. If an IPv4 route then attempts to reference this nexthop, it causes a NULL pointer...
