kernel: macvlan: fix error recovery in macvlan_common_newlink()

A use-after-free vulnerability was found in the macvlan driver. When creating a macvlan interface in source mode fails after the source MAC has been added to the hash table e.g., due to an invalid interface name, the hash entry still references the freed netdevice structure. Subsequent packets...

BIT-MONGODB-2026-4358 Memory safety issues in slot-based execution hash table spill

A specially crafted aggregation query with $lookup by an authenticated user with write privileges can cause a double-free or use-after-free memory issue in the slot-based execution SBE engine when an in-memory hash table is spilled to disk...

CVE-2026-23331

A flaw was found in the Linux kernel's handling of User Datagram Protocol UDP sockets. When an auto-bound UDP socket is connected and subsequently disconnected, it may not be properly unhashed from the 4-tuple hash table. This oversight can lead to the accumulation of stale entries, potentially...

SUSE CVE-2026-23331

In the Linux kernel, the following vulnerability has been resolved: udp: Unhash auto-bound connected sk from 4-tuple hash table when disconnected. Let's say we bind an UDP socket to the wildcard address with a non-zero port, connect it to an address, and disconnect it from the address. bind sets...

CVE-2026-23331

The CVE-2026-23331 issue concerns the Linux kernel UDP 4-tuple hash table: when an auto-bound UDP socket is bound, connected, and then disconnected, the socket may be moved to a new hash slot without removing the old entry, leaving garbage in the 4-tuple chain. The fix is to remove such a socket ...
