Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 460689

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: cpufreq: pcc: fix use-after-free and
 double free in _OSC evaluation pcc_cpufreq_do_osc() calls acpi_evaluate_object() twice for the two-phase
 _OSC negotiation. Between the two calls it freed output.pointer but left output.length unchanged. Since
 acpi_evaluate_object() treats a non-zero length with a non-NULL pointer as an existing buffer to write
 into, the second call wrote into freed memory (use-after-free). The subsequent kfree(output.pointer) at
 out_free then freed the same pointer a second time (double free). Reset output.pointer to NULL and
 output.length to ACPI_ALLOCATE_BUFFER after freeing the first result, so ACPICA allocates a fresh buffer
 for each phase independently. (CVE-2026-64372)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
