medium Tenable Cloud Security Plugin ID 468571

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: net: bridge: Reject descending VLAN
tunnel ranges A pair of descending VLAN and tunnel IDs can pass the tunnel range span check. The VLAN
subtraction produces a negative int, which is converted to unsigned when compared with the u32 tunnel ID
subtraction. It can therefore equal the wrapped tunnel ID delta. The range loop then performs no
iterations. Since the batched notification handling added a post-loop error check, this leaves err
uninitialized and makes the request's return value unpredictable. Reject descending VLAN ranges before
comparing the spans. Valid ascending and single-entry ranges remain unchanged, while malformed descending
ranges consistently return -EINVAL. This issue was found by a static analysis checker and confirmed by
manual source review. (CVE-2026-90114)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
