Title
drm/amd/display: fix null-pointer dereference on edid reading
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix null-pointer dereference on edid reading
Use i2c adapter when there isn't aux_mode in dc_link to fix a
null-pointer derefence that happens when running
igt@kms_force_connector_basic in a system with DCN2.1 and HDMI connector
detected as below:

No network or adjacent-network reachability exists.\nAC:L - The confused pointer is computed deterministically on every forced probe with no race, no timing window, and no dependence on memory layout the attacker cannot influence; the attacker simply repeats the probe.\nPR:L - On systems where the connector is forced at boot via the documented `video=\u003cconnector\u003e:e` parameter (routine for kiosk, digital-signage, automotive and industrial panels with no HPD), an unprivileged local user with /dev/dri access holding DRM master re-triggers `fill_modes()` \u2192 `.force()` and `mode_valid()` \u2192 `create_eml_sink()` with no elevated capability; the root sysfs write is only one of several ways the forced state gets established.\nUI:N - The attacker performs the triggering ioctl or sysfs write themselves; no victim action, mount, or file-open is required to reach the faulting code.\nS:U - The type confusion, the wild dereference, and the resulting crash or control-flow hijack all occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The bogus `i2c_adapter *` points into the 2048-byte monitor-supplied `dc_edid.raw_edid` buffer, so `adap-\u003ealgo` at raw_edid+0x4c0 is display-controlled and is dereferenced by i2c_transfer(), giving an arbitrary kernel-address read; a successful transfer would additionally populate the EDID buffer from kernel memory.\nI:H - `__i2c_transfer()` invokes `adap-\u003ealgo-\u003emaster_xfer()` and `__i2c_lock_bus_helper()` invokes `adap-\u003elock_ops-\u003elock_bus()` through function pointers read from that attacker-influenced EDID data, yielding a control-flow hijack primitive leading to arbitrary kernel code execution.\nA:H - In the common case the code dereferences NULL+0x4b0 and oopses while holding `dev-\u003emode_config.mutex` and the modeset `connection_mutex`, so the entire DRM subsystem deadlocks afterwards and every subsequent DRM open/ioctl hangs unkillably."

No network or adjacent-network reachability exists.\\nAC:L - The confused pointer is computed deterministically on every forced probe with no race, no timing window, and no dependence on memory layout the attacker cannot influence; the attacker simply repeats the probe.\\nPR:L - On systems where the connector is forced at boot via the documented `video=\u003cconnector\u003e:e` parameter (routine for kiosk, digital-signage, automotive and industrial panels with no HPD), an unprivileged local user with /dev/dri access holding DRM master re-triggers `fill_modes()` \\u2192 `.force()` and `mode_valid()` \\u2192 `create_eml_sink()` with no elevated capability; the root sysfs write is only one of several ways the forced state gets established.\\nUI:N - The attacker performs the triggering ioctl or sysfs write themselves; no victim action, mount, or file-open is required to reach the faulting code.\\nS:U - The type confusion, the wild dereference, and the resulting crash or control-flow hijack all occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - The bogus `i2c_adapter *` points into the 2048-byte monitor-supplied `dc_edid.raw_edid` buffer, so `adap-\u003ealgo` at raw_edid+0x4c0 is display-controlled and is dereferenced by i2c_transfer(), giving an arbitrary kernel-address read; a successful transfer would additionally populate the EDID buffer from kernel memory.\\nI:H - `__i2c_transfer()` invokes `adap-\u003ealgo-\u003emaster_xfer()` and `__i2c_lock_bus_helper()` invokes `adap-\u003elock_ops-\u003elock_bus()` through function pointers read from that attacker-influenced EDID data, yielding a control-flow hijack primitive leading to arbitrary kernel code execution.\\nA:H - In the common case the code dereferences NULL+0x4b0 and oopses while holding `dev-\u003emode_config.mutex` and the modeset `connection_mutex`, so the entire DRM subsystem deadlocks afterwards and every subsequent DRM open/ioctl hangs unkillably.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0e859faf8670a78ce206977dcf1a31a0231e9ca5\", \"lessThan\": \"2d392f7268a1a9bfbd98c831f0f4c964e59aa145\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0e859faf8670a78ce206977dcf1a31a0231e9ca5\", \"lessThan\": \"9671761792156f2339627918bafcd713a8a6f777\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.7\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.7\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.7.7\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/2d392f7268a1a9bfbd98c831f0f4c964e59aa145\"}, {\"url\": \"https://git.kernel.org/stable/c/9671761792156f2339627918bafcd713a8a6f777\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm/amd/display: fix null-pointer dereference on edid reading\\n\\nUse i2c adapter when there isn\u0027t aux_mode in dc_link to fix a\\nnull-pointer derefence that happens when running\\nigt@kms_force_connector_basic in a system with DCN2.1 and HDMI connector\\ndetected as below:\\n\\n[ +0.178146] BUG: kernel NULL pointer dereference, address: 00000000000004c0\\n[ +0.000010] #PF: supervisor read access in kernel mode\\n[ +0.000005] #PF: error_code(0x0000) -
