A vulnerability in the REST API of Cisco Secure FMC Software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system.
This vulnerability is due to inadequate validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests to an affected device. A successful exploit could allow the attacker to obtain read access to the database and read certain files on the underlying operating system. To exploit this vulnerability, the attacker would need valid user credentials with any of the following roles:
Administrator
Security approver
Access admin
Network admin

CVE-2026-98595 [LOW] CWE-459 kernel: udp: remove a disconnected socket from the 4-tuple hash table
kernel: udp: remove a disconnected socket from the 4-tuple hash table
In the Linux kernel, the following vulnerability has been resolved:
udp: remove a disconnected socket from the 4-tuple hash table
A UDP socket bound to a specific address and port keeps its entry in the
4-tuple hash table after it is disconnected:
sk binds to 127.0.0.1:21001
sk connects to 127.0.0.2:20001// filed in the 4-tuple table
sk disconnects, connect(AF_UNSPEC)// still filed, peer now 0.0.0.0:0
__udp_disconnect() takes a socket out of that table only as a side effect
of ->rehash() or ->unhash(), and it skips ->rehash() when
SOCK_BINDADDR_LOCK is set and ->unhash() when SOCK_BINDPORT_LOCK is set.
commit 6996a2d2d0a6 ("udp: Unhash auto-bound connected sk from 4-tuple hash
table when disconnected.") fixed the same e
