(amdgpu_device_ip_init \u2192 si_dpm_sw_init \u2192 si_dpm_init \u2192 si_parse_power_table) on Southern Islands GPUs; suspend/resume and GPU reset use hw callbacks and do not re-parse the power table, and no network path exists.\nAC:L - A local attacker can induce system-wide memory pressure so a mid-loop GFP_KERNEL kzalloc of struct si_ps fails; once that happens, the premature kfree of adev->pm.dpm.ps followed by si_dpm_fini\u2019s second free is deterministic with no uncontrolled race.\nPR:L - Scored from an unprivileged local account on a shared system with an affected SI GPU under the higher-severity interpretation, consistent with sibling double-frees CVE-2023-52691 and CVE-2023-52469; real root is not required for the attacker\u2019s privileges prior to exploitation.\nUI:N - No separate victim action such as opening a file or mounting a device is required; the flaw is triggered by driver initialization under attacker-influenced memory conditions.\nS:U - Impact remains within the host kernel\u2019s security authority as standard kernel heap corruption / privilege escalation, with no VM escape, IOMMU bypass, or other security-boundary crossing.\nC:H - Double-free of the adev->pm.dpm.ps heap object (with a dangling non-NULL pointer) is UAF-class memory corruption; reclaiming the freed slab enables arbitrary kernel read primitives.\nI:H - Double-free freelist corruption in the kernel allocator can be abused for overlapping objects and arbitrary write / control-flow hijacking, enabling full integrity compromise and privilege escalation.\nA:H - The double-free reliably corrupts kernel heap state and can oops/panic the kernel even when not fully exploited for code execution, which is Availability High under kernel CVSS guidance."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git",
