CVE-2025-68204 Vulnerability Summary
CVE-2025-68204: In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fix genpd leak on provider registration failure If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add(). Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure. Example crash trace observed without this fix: | Unable to handle kernel paging request at virtual address fffffffffffffc70 | CPU: 1 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.18.0-rc1 #405 PREEMPT | Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform | pstate: 00000005 (nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) | pc : genpd_debug_add+0x2c/0x160 | lr : genpd_debug_init+0x74/0x98 | Call trace: | genpd_debug_add+0x2c/0x160 (P) | genpd_debug_init+0x74/0x98 | do_one_initcall+0xd0/0x2d8 | do_initcall_level+0xa0/0x140 | do_initcalls+0x60/0xa8 | do_basic_setup+0x28/0x40 | kernel_init_freeable+0xe8/0x170 | kernel_init+0x2c/0x140 | ret_from_fork+0x10/0x20
Assessing the Risk of CVE-2025-68204
Access Complexity Graph
The exploitability of CVE-2025-68204 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
Exploitability Analysis for CVE-2025-68204
No exploitability data is available for CVE-2025-68204.
Understanding AC and PR
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
CVSS Score Breakdown Chart
Above is the CVSS Sub-score Breakdown for CVE-2025-68204, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
