Vulnerability from cvelistv5
Published

Modified

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: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set() The kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8 bytes via memset without checking the buffer size parameter. This allows unprivileged userspace to trigger an out-of bounds kernel memory write by passing a small buffer, leading to potential privilege escalation.

There is no network, adjacent, or physical packet/device-input path.\nAC:L - The attacker controls the supplied event-page handle and can allocate a buffer smaller than `KFD_SIGNAL_EVENT_LIMIT * 8`, making the fixed-size `memset` out-of-bounds deterministic. No race or external condition is required.\nPR:L - The path is available to unprivileged userspace with access to KFD/AMDGPU device nodes, and the relevant ioctls have no capability flag or `capable()` gate. This is low privilege, not real administrator privilege.\nUI:N - Once a local attacker can execute code and open the device, exploitation only requires issuing ioctls. No victim user action is needed.\nS:U - The corruption occurs inside the kernel driver and impacts the same kernel security authority. This is standard local kernel compromise/DoS, not a cross-scope escape such as guest-to-host or IOMMU boundary bypass.\nC:H - The bug is an out-of-bounds kernel write into memory adjacent to a kernel-mapped GPU buffer, and kernel memory corruption can reasonably be leveraged to disclose sensitive kernel memory. Following the higher-severity rule for memory corruption, confidentiality impact is High.\nI:H - The vulnerable `memset` writes attacker-triggered data beyond the allocated object, giving a kernel memory corruption primitive. Out-of-bounds writes are scored as High integrity impact because they can plausibly be developed into privilege escalation or control-flow/data corruption.\nA:H - The out-of-bounds kernel write can corrupt adjacent kernel memory and readily crash or destabilize the kernel even without full exploitation. Kernel oops, panic, or persistent GPU/kernel failure is a High availability impact."

There is no network, adjacent, or physical packet/device-input path.\\nAC:L - The attacker controls the supplied event-page handle and can allocate a buffer smaller than `KFD_SIGNAL_EVENT_LIMIT * 8`, making the fixed-size `memset` out-of-bounds deterministic. No race or external condition is required.\\nPR:L - The path is available to unprivileged userspace with access to KFD/AMDGPU device nodes, and the relevant ioctls have no capability flag or `capable()` gate. This is low privilege, not real administrator privilege.\\nUI:N - Once a local attacker can execute code and open the device, exploitation only requires issuing ioctls. No victim user action is needed.\\nS:U - The corruption occurs inside the kernel driver and impacts the same kernel security authority. This is standard local kernel compromise/DoS, not a cross-scope escape such as guest-to-host or IOMMU boundary bypass.\\nC:H - The bug is an out-of-bounds kernel write into memory adjacent to a kernel-mapped GPU buffer, and kernel memory corruption can reasonably be leveraged to disclose sensitive kernel memory. Following the higher-severity rule for memory corruption, confidentiality impact is High.\\nI:H - The vulnerable `memset` writes attacker-triggered data beyond the allocated object, giving a kernel memory corruption primitive. Out-of-bounds writes are scored as High integrity impact because they can plausibly be developed into privilege escalation or control-flow/data corruption.\\nA:H - The out-of-bounds kernel write can corrupt adjacent kernel memory and readily crash or destabilize the kernel even without full exploitation. Kernel oops, panic, or persistent GPU/kernel failure is a High availability impact.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"3e04bc310d80b46eaf481f1fefcbcb37a187412d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"de8d7a25cd2eb5875b1d8d4fbc7fe4b4138b781f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"b4034442cb090e4a980bdcc1540948606cbc951b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"4857c37c7ba9aa38b9a4c694e8bd8d0091c87940\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"75fb57efdd7863fffbc39db23e9cad7aafda26ed\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"bfcd6b53e1f4feb182952f4ff9a137c36ceaf20b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"4e72f419e4ed44cb3b60506752d8688c20a60a9b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0fc8011f89feb8b2c3008583b777d097e1974660\", \"lessThan\": \"8a70a26c9f34baea6c3199a9862ddaff4554a96d\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/amd/amdkfd/kfd_events.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.17\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.17\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.252\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.202\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.165\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.128\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.75\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.16\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"6.19.6\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.19.*\"}, {\"status\": \"unaffected\", \"version\": \"7.0\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/amd/amdkfd/kfd_events.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/3e04bc310d80b46eaf481f1fefcbcb37a187412d\"}, {\"url\": \"https://git.kernel.org/stable/c/de8d7a25cd2eb5875b1d8d4fbc7fe4b4138b781f\"}, {\"url\": \"https://git.kernel.org/stable/c/b4034442cb090e4a980bdcc1540948606cbc951b\"}, {\"url\": \"https://git.kernel.org/stable/c/4857c37c7ba9aa38b9a4c694e8bd8d0091c87940\"}, {\"url\": \"https://git.kernel.org/stable/c/75fb57efdd7863fffbc39db23e9cad7aafda26ed\"}, {\"url\": \"https://git.kernel.org/stable/c/bfcd6b53e1f4feb182952f4ff9a137c36ceaf20b\"}, {\"url\": \"https://git.kernel.org/stable/c/4e72f419e4ed44cb3b60506752d8688c20a60a9b\"}, {\"url\": \"https://git.kernel.org/stable/c/8a70a26c9f34baea6c3199a9862ddaff4554a96d\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()\\n\\nThe kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8\\nbytes via memset without checking the buffer size parameter.
