high Tenable Cloud Security Plugin ID 472615

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: vxlan: vnifilter: enforce exact length
 of GROUP/GROUP6 attributes The VXLAN VNI filter entry policy declares the GROUP/GROUP6 address attributes
 as NLA_BINARY with only a maximum length, so validate_nla() accepts a payload shorter than the address.
 The GROUP consumer reads it with nla_get_in_addr(), an unconditional 4-byte load, so a short attribute
 over-reads up to 3 bytes of uninitialised slab data, which are stored into remote_ip and echoed back via
 RTM_GETTUNNEL, disclosing kernel memory. Switch both entries to NLA_POLICY_EXACT_LEN() so the validator
 rejects any GROUP/GROUP6 that is not exactly 4 / 16 bytes; a valid address is always sent at full width.
 (CVE-2026-89776)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.624.2 or later.
