Those GPIOs do not\nhave a corresponding MPM pin and should not be handled inside the MPM\ndriver. The IRQ domain hierarchy is always applied, so it's required to\nexplicitly disconnect the hierarchy for those. The pinctrl-msm driver marks\nthese with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but\nirq-qcom-mpm is currently missing the check.

There is no network or adjacent-network path to `qcom_mpm_set_type()`.\nAC:L - Triggering is fully deterministic — a single `gpiomon -c gpiochipN ` on any GPIO absent from the SoC's `wakeirq_map` reliably reaches the out-of-bounds access, and non-wake lines are the majority on these SoCs and are trivially enumerable. No race, no memory-layout condition outside the attacker's control is needed for the corruption/crash.\nPR:L - The attacker only needs open access to `/dev/gpiochipN`, which on the embedded, robotics and IoT platforms that actually ship Qualcomm MPM is routinely granted to an unprivileged `gpio`-group account or service user via standard udev rules (0660 root:gpio) so that libgpiod consumers can run without root. No capability check exists anywhere along the path once the device node is opened.\nUI:N - The attacker performs the ioctl themselves in a single step; no victim action, configuration change, or interaction from another user is required.\nS:U - The out-of-bounds access corrupts kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - `__assign_bit(0xFFFFFFFF, &val, ...)` performs a read-modify-write 511 MB beyond a kernel stack local, i.e. an unbounded out-of-bounds read of an arbitrary vmalloc-region word; combined with the accompanying write primitive this constitutes memory corruption that can be leveraged to disclose kernel memory.\nI:H - This is an out-of-bounds write: bit 63 of the unsigned long at a fixed +0x1FFFFFF8 offset from the kernel stack is set or cleared under attacker control (via the EDGE_RISING/EDGE_FALLING line flags), repeatably. With vmap'd stacks and vmalloc grooming, flipping the top bit of a pointer, length, or refcount in a neighbouring object is a real control-flow-corruption primitive.\nA:H - The reported and reproducible outcome is a kernel paging fault (\"Unable to handle kernel paging request\") in `mpm_set_type`, an oops taken inside `raw_spin_lock_irqsave(&priv->lock)` with interrupts disabled — so `priv->lock` is orphaned and all later MPM operations, including the wake handler and the suspend path, deadlock." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/irqchip/irq-qcom-mpm.c" ], "versions": [ { "version": "a6199bb514d8a63f61c2a22c1f912376e14d0fb2", "lessThan": "45aced97f01d5ab14c8a2a60f6748f18c501c3f5", "status": "affected", "versionType": "git" }, { "version": "a6199bb514d8a63f61c2a22c1f912376e14d0fb2", "lessThan": "dfbaecf7e38f5e9bfa5e47a1e525ffbb58bab8cf", "status": "affected", "versionType": "git" }, { "version": "a6199bb514d8a63f61c2a22c1f912376e14d0fb2", "lessThan": "f102342360950b56959e5fff4a874ea88ae13758", "status": "affected", "versionType": "git" }, { "version": "a6199bb514d8a63f61c2a22c1f912376e14d0fb2", "lessThan": "d5c10448f411a925dd59005785cb971f0626e032", "status": "affected", "versionType": "git" }, { "version": "a6199bb514d8a63f61c2a22c1f912376e14d0fb2", "lessThan": "38a05c0b87833f5b188ae43b428b1f792df2b384", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/irqchip/irq-qcom-mpm.c" ], "versions": [ { "version": "5.18", "status": "affected" }, { "version": "0", "lessThan": "5.18", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.138", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.90", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.28", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.14.6", "lessThanOrEqual": "6.14.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.15", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.1.138" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.6.90" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.12.28" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.14.6" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.15" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/45aced97f01d5ab14c8a2a60f6748f18c501c3f5" }, { "url": "https://git.kernel.org/stable/c/dfbaecf7e38f5e9bfa5e47a1e525ffbb58bab8cf" }, { "url": "https://git.kernel.org/stable/c/f102342360950b56959e5fff4a874ea88ae13758" }, { "url": "https://git.kernel.org/stable/c/d5c10448f411a925dd59005785cb971f0626e032" }, { "url": "https://git.kernel.org/stable/c/38a05c0b87833f5b188ae43b428b1f792df2b384" } ], "title": "irqchip/qcom-mpm: Prevent crash when trying to handle non-wake GPIOs", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/08/msg00010.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T19:57:06.588Z" } } ] } }
