CVSS Release:
CVE-2025-37898: In the Linux kernel, the following vulnerability has been resolved: powerpc64/ftrace: fix module loading without patchable function entries get_stubs_size assumes that there must always be at least one patchable function entry, which is not always the case (modules that export data but no code), otherwise it returns -ENOEXEC and thus the section header sh_size is set to that value. During module_memory_alloc() the size is passed to execmem_alloc() after being page-aligned and thus set to zero which will cause it to fail the allocation (and thus module loading) as __vmalloc_node_range() checks for zero-sized allocs and returns null: [ 115.466896] module_64: cast_common: doesn't contain __patchable_function_entries. [ 115.469189] ------------[ cut here ]------------ [ 115.469496] WARNING: CPU: 0 PID: 274 at mm/vmalloc.c:3778 __vmalloc_node_range_noprof+0x8b4/0x8f0 ... [ 115.478574] ---[ end trace 0000000000000000 ]--- [ 115.479545] execmem: unable to allocate memory Fix this by removing the check completely, since it is anyway not helpful to propagate this as an error upwards.
The exploitability of CVE-2025-37898 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).
No exploitability data is available for CVE-2025-37898.
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.
Above is the CVSS Sub-score Breakdown for CVE-2025-37898, 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.
Below is the Impact Analysis for CVE-2025-37898, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
