Vulnerability from cvelistv5
Published

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group The perf tool allows users to create event groups through following cmd [1], but the driver does not check whether the array index is out of bounds when writing data to the event_group array. If the number of events in an event_group is greater than HISI_PCIE_MAX_COUNTERS, the memory write overflow of event_group array occurs. Add array index check to fix the possible array out of bounds violation, and return directly when write new events are written to array bounds. There are 9 different events in an event_group. [1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}'

no network or remote-peer data is involved.\\nAC:L - Triggering is fully deterministic \\u2014 open a group leader plus 7 distinct hisi_pcie events, then open a 9th distinct event \\u2014 with no race, timing window, or memory-layout condition outside the attacker\u0027s control.\\nPR:L - On the profiling/HPC/Kunpeng-server deployments where this PMU driver is actually used, `kernel.perf_event_paranoid` is commonly set to 0 or -1, which makes `perf_allow_cpu()` pass for any unprivileged local user; only that (not real root) is needed to build the oversized event group.\\nUI:N - The attacker performs the entire nine-syscall sequence itself; no victim action or cooperation is required.\\nS:U - The out-of-bounds write corrupts the kernel\u0027s own stack within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - The overflow is stack memory corruption adjacent to saved registers and spilled pointers, which per kernel scoring practice can be leveraged toward disclosure of kernel memory and defeats stack-layout confidentiality assumptions.\\nI:H - This is an out-of-bounds stack write that places an attacker-groomed kernel heap pointer over the canary/saved-register slot above the array, i.e. corruption of control-flow-relevant stack state.\\nA:H - On stack-protector-enabled arm64 builds the OOB write clobbers the canary and reliably triggers `__stack_chk_fail()` \\u2192 kernel panic, and it can be repeated at will from userspace.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a\", \"lessThan\": \"3d1face00ebb7996842aee4214d7d0fb0c77b1e9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a\", \"lessThan\": \"8e9aab2492178f25372f1820bfd9289fbd74efd0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a\", \"lessThan\": \"567d34626c22b36579ec0abfdf5eda2949044220\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a\", \"lessThan\": \"ff48247144d13a3a0817127703724256008efa78\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a\", \"lessThan\": \"77fce82678ea5fd51442e62febec2004f79e041b\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/perf/hisilicon/hisi_pcie_pmu.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.17\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.17\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.93\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.33\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.9.*\"}, {\"status\": \"unaffected\", \"version\": \"6.10\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/perf/hisilicon/hisi_pcie_pmu.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/3d1face00ebb7996842aee4214d7d0fb0c77b1e9\"}, {\"url\": \"https://git.kernel.org/stable/c/8e9aab2492178f25372f1820bfd9289fbd74efd0\"}, {\"url\": \"https://git.kernel.org/stable/c/567d34626c22b36579ec0abfdf5eda2949044220\"}, {\"url\": \"https://git.kernel.org/stable/c/ff48247144d13a3a0817127703724256008efa78\"}, {\"url\": \"https://git.kernel.org/stable/c/77fce82678ea5fd51442e62febec2004f79e041b\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrivers/perf: hisi_pcie: Fix out-of-bound access when valid event group\\n\\nThe perf tool allows users to create event groups through following\\ncmd [1], but the driver does not check whether the array index is out of\\nbounds when writing data to the event_group array.
