high Tenable Self-Hosted Container Security Plugin ID 475139

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: iommu/tegra241-cmdqv: Reject a vSID
 wider than the SID_MATCH field tegra241_vintf_init_vsid() programs the guest-provided vSID into SID_MATCH,
 whose VIRT_SID field spans bits [20:1] with bit 0 as the match-enable flag. The HW therefore matches only
 a 20-bit Stream ID. The bound check rejects only virt_sid > UINT_MAX, which admits a value far wider than
 the field. The write "virt_sid << 1 | 0x1" then drops every bit above 20: a virt_sid of 0x80000000 lands
 as SID_MATCH = 0x1, a valid match on vSID 0, so the entry aliases the wrong Stream ID. Because
 vdev->virt_id is guest-controlled, a VMM can trigger it. Validate virt_sid against the field width with
 FIELD_MAX(), and program the register with FIELD_PREP() so the value and the field stay consistent.
 (CVE-2026-89450)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.106 or later.
