DescriptionCVE.org

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.

AnalysisAI

Local privilege escalation in the Linux kernel's pcc-cpufreq driver allows a low-privileged user to gain full root privileges. The vulnerability is a use-after-free and double-free flaw when evaluating ACPI _OSC negotiation, affecting all kernel versions from 2.6.34 until the fixed stable releases (5.10.261, 5.15.212, 6.1.178, 6.6.145, 6.12.96, 6.18.39, 7.1.4, and 7.2-rc1). No active exploitation or public exploit has been identified, and EPSS indicates a low probability of widespread exploitation.
