CVE-2026-43294: drm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panels

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 3cd7a71958c9f7f1def1a110e1ac98c022a554cd, 41cda667ffc5074c56279c632b0c20024da6ecdd, 64aa8b3a60a825134f7d866adf05c024bbe0c24c; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3cd7a71958c9f7f1def1a110e1ac98c022a554cd, 41cda667ffc5074c56279c632b0c20024da6ecdd, 64aa8b3a60a825134f7d866adf05c024bbe0c24c; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

In the Linux kernel, the following vulnerability has been resolved: drm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panels Since commit 56de5e305d4b ("clk: renesas: r9a07g044: Add MSTOP for RZ/G2L") we may get the following kernel panic, for some panels, when rebooting: systemd-shutdown[1]: Rebooting. Call trace: ... do_serror+0x28/0x68 el1h_64_error_handler+0x34/0x50 el1h_64_error+0x6c/0x70 rzg2l_mipi_dsi_host_transfer+0x114/0x458 (P) mipi_dsi_device_transfer+0x44/0x58 mipi_dsi_dcs_set_display_off_multi+0x9c/0xc4 ili9881c_unprepare+0x38/0x88 drm_panel_unprepare+0xbc/0x108 This happens for panels that need to send MIPI-DSI commands in their unprepare() callback. Since the MIPI-DSI interface is stopped at that point, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic. Fix by moving rzg2l_mipi_dsi_stop() to new callback function rzg2l_mipi_dsi_atomic_post_disable(). With this change we now have the correct power-down/stop sequence: systemd-shutdown[1]: Rebooting. rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry reboot: Restarting system

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
