Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.0.99

medium Tenable Cloud Security Plugin ID 472347

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: mm: avoid leaving partial pfn mappings
 around in error case As Jann points out, PFN mappings are special, because unlike normal memory mappings,
 there is no lifetime information associated with the mapping - it is just a raw mapping of PFNs with no
 reference counting of a 'struct page'. That's all very much intentional, but it does mean that it's easy
 to mess up the cleanup in case of errors. Yes, a failed mmap() will always eventually clean up any partial
 mappings, but without any explicit lifetime in the page table mapping itself, it's very easy to do the
 error handling in the wrong order. In particular, it's easy to mistakenly free the physical backing store
 before the page tables are actually cleaned up and (temporarily) have stale dangling PTE entries. To make
 this situation less error-prone, just make sure that any partial pfn mapping is torn down early, before
 any other error handling. (CVE-2024-47674)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.0.99 or later.
