Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.236.44

high Tenable Self-Hosted Container Security Plugin ID 451569

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: KVM: nSVM: Ignore nCR3[4:0] when
loading PDPTEs from memory Ignore nCR3[4:0] when loading PDPTEs from memory for nested SVM, as bits 4:0 of
CR3 are ignored when PAE paging is used, and thus VMRUN doesn't enforce 32-byte alignment of nCR3. In the
absolute worst case scenario, failure to ignore bits 4:0 can result in an out-of-bounds read, e.g. if the
target page is at the end of a memslot, and the VMM isn't using guard pages. Per the APM: The CR3 register
points to the base address of the page-directory-pointer table. The page-directory-pointer table is
aligned on a 32-byte boundary, with the low 5 address bits 4:0 assumed to be 0. And the SDM's much more
explicit: 4:0 Ignored Note, KVM gets this right when loading PDPTRs, it's only the nSVM flow that is
broken. (CVE-2024-50115)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.236.44 or later.
