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: ACPICA: fix acpi operand cache leak in
dswstate.c ACPICA commit 987a3b5cf7175916e2a4b6ea5b8e70f830dfe732 I found an ACPI cache leak in ACPI early
termination and boot continuing case. When early termination occurs due to malicious ACPI table, Linux
kernel terminates ACPI function and continues to boot process. While kernel terminates ACPI function,
kmem_cache_destroy() reports Acpi-Operand cache leak. Boot log of ACPI operand cache leak is as follows:

this memory leak in detail and found acpi_ds_obj_stack_pop_and_ delete() function miscalculated the top of
the stack. acpi_ds_obj_stack_push() function uses walk_state->operand_index for start position of the top,
but acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it. Therefore, this causes acpi
operand memory leak. This cache leak causes a security threat because an old kernel (<= 4.9) shows memory
locations of kernel functions in stack dump. Some malicious users could use this information to neutralize
kernel ASLR. I made a patch to fix ACPI operand cache leak. (CVE-2025-38345)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.339.11 or later.
