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: platform/x86: x86-android-tablets: Fix use after free on platform_device_register() errors x86_android_tablet_remove() frees the pdevs[] array, so it should not be used after calling x86_android_tablet_remove(). When platform_device_register() fails, store the pdevs[x] PTR_ERR() value into the local ret variable before calling x86_android_tablet_remove() to avoid using pdevs[] after it has been freed.

This is a use-after-free read of freed slab memory whose contents an attacker can influence via heap grooming, and the false-success cascade leaves five dangling global pointers that are later dereferenced, giving a path to disclosing arbitrary reclaimed kernel data.\\nI:H - When the freed slot reads back as zero the probe falsely reports success, so `x86_android_tablet_remove()` runs a second time and double-frees five allocations while unregistering devices from freed arrays \\u2014 a double-free/UAF-write primitive that is the classic basis for slab corruption and control-flow hijack.\\nA:H - The use-after-free read produces a KASAN report (a panic with `kasan.fault=panic`/`panic_on_warn`), and the downstream double-free and unregistration of stale device pointers reliably oops or panics the kernel.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5eba0141206ea521bbcfcf5067c174e825e943dd\", \"lessThan\": \"ba0b09a2f327319e252d8f3032019b958c0a5cd9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5eba0141206ea521bbcfcf5067c174e825e943dd\", \"lessThan\": \"aac871e493fc8809e60209d9899b1af07e9dbfc8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5eba0141206ea521bbcfcf5067c174e825e943dd\", \"lessThan\": \"f08adc5177bd4343df09033f62ab562c09ba7f7d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5eba0141206ea521bbcfcf5067c174e825e943dd\", \"lessThan\": \"73a98cf79e4dbfa3d0c363e826c65aae089b313c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5eba0141206ea521bbcfcf5067c174e825e943dd\", \"lessThan\": \"2fae3129c0c08e72b1fe93e61fd8fd203252094a\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/platform/x86/x86-android-tablets/core.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\": \"6.1.118\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.55\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.10.14\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.10.*\"}, {\"status\": \"unaffected\", \"version\": \"6.11.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.11.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/platform/x86/x86-android-tablets/core.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/ba0b09a2f327319e252d8f3032019b958c0a5cd9\"}, {\"url\": \"https://git.kernel.org/stable/c/aac871e493fc8809e60209d9899b1af07e9dbfc8\"}, {\"url\": \"https://git.kernel.org/stable/c/f08adc5177bd4343df09033f62ab562c09ba7f7d\"}, {\"url\": \"https://git.kernel.org/stable/c/73a98cf79e4dbfa3d0c363e826c65aae089b313c\"}, {\"url\": \"https://git.kernel.org/stable/c/2fae3129c0c08e72b1fe93e61fd8fd203252094a\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nplatform/x86: x86-android-tablets: Fix use after free on platform_device_register() errors\\n\\nx86_android_tablet_remove() frees the pdevs[] array, so it should not\\nbe used after calling x86_android_tablet_remove().\\n\\nWhen platform_device_register() fails, store the pdevs[x] PTR_ERR() value\\ninto the local ret variable before calling x86_android_tablet_remove()\\nto avoid using pdevs[] after it has been freed.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.118\", \"versionStartIncluding\": \"5.17\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.55\", \"versionStartIncluding\": \"5.17\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.10.14\", \"versionStartIncluding\": \"5.17\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.11.3\", \"versionStartIncluding\": \"5.17\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12\", \"versionStartIncluding\": \"5.17\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:40:54.750Z\"}}}",
