kernel: udp: Fix wildcard bind conflict check when using hash2

A flaw was found in the Linux kernel's User Datagram Protocol UDP implementation. When a significant number of UDP sockets are bound to specific local addresses on the same port, the kernel's conflict detection mechanism can fail. This allows a local attacker to bind to a wildcard address on a po...

AZL-83351 CVE-2026-31503 affecting package kernel for versions less than 6.6.134.1-2

In the Linux kernel, the following vulnerability has been resolved: udp: Fix wildcard bind conflict check when using hash2 When binding a udpsock to a local address and port, UDP uses two hashes udptable-hash and udptable-hash2 for collision detection. The current code switches to "hash2" when...

The vulnerability of the check_port_conflict() function (/goform/check_port_conflict) in the microprogramming software for Linksys routers RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 allows a attacker to execute arbitrary code.

The vulnerability of the checkportconflict function /goform/checkportconflict in the microprogramming software for Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 is related to buffer overflow in the stack. Exploiting this vulnerability could allow an attacker to execute arbitrary code...
