CVE-2026-89866: media: chips-media: wave5: Resume device before setting EOS flag

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 2215e55ee1e5e69ad53862d968360c5aa63dd3a7, 56c2c5ad35614ca5ae23838d6af5d7f59e3124dc, 9c757d77a6eb58ca4a47cada5ab60451e6c2d247.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2215e55ee1e5e69ad53862d968360c5aa63dd3a7, 56c2c5ad35614ca5ae23838d6af5d7f59e3124dc, 9c757d77a6eb58ca4a47cada5ab60451e6c2d247 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Resume device before setting EOS flag Setting the EOS flag talks to the firmware via send_firmware_command(), which accesses VPU registers. Both the STREAMOFF path (wave5_vpu_dec_job_abort()) and the V4L2_DEC_CMD_STOP path (wave5_vpu_dec_stop()) can run while the device is runtime suspended, so those register accesses hit powered-down hardware and the SoC raises an asynchronous SError, panicking the kernel: SError Interrupt on CPU3, code 0x00000000bf000000 -- SError send_firmware_command+0x2c/0x160 [wave5] wave5_vpu_dec_set_bitstream_flag+0x6c/0x80 [wave5] wave5_vpu_dec_update_bitstream_buffer+0x80/0xec [wave5] wave5_vpu_dec_job_abort+0x44/0xa0 [wave5] v4l2_m2m_cancel_job+0x110/0x19c [v4l2_mem2mem] v4l2_m2m_streamoff+0x24/0x140 [v4l2_mem2mem] Resume the device with pm_runtime_resume_and_get() around the EOS firmware command and release it with pm_runtime_put_autosuspend(), matching the runtime PM handling already done in wave5_vpu_dec_device_run().
