Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.236.26

medium Tenable Cloud Security Plugin ID 450732

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: efistub/tpm: Use ACPI reclaim memory
for event log to avoid corruption The TPM event log table is a Linux specific construct, where the data
produced by the GetEventLog() boot service is cached in memory, and passed on to the OS using an EFI
configuration table. The use of EFI_LOADER_DATA here results in the region being left unreserved in the
E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the
incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the
utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code
off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always
treated as reserved by the E820 conversion logic. (CVE-2024-49858)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.236.26 or later.
