CVE-2026-72245: gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path

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: 0.23% (FIRST EPSS).
  • Fixed version: Linux Linux 3642d0a45214e3b4cf61bf5e75b04b490d0b3519, 4454caa204a2edb19c62754ddb96e5dbca0d2f49, 4ee41361c637eafa80f5d88b46d0016e6cdb24db.

Low priority for now. Upgrade to Linux Linux 3642d0a45214e3b4cf61bf5e75b04b490d0b3519, 4454caa204a2edb19c62754ddb96e5dbca0d2f49, 4ee41361c637eafa80f5d88b46d0016e6cdb24db or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path After device_initialize(), the embedded struct device in struct host1x_device should be released through the device core with put_device(). In host1x_device_add(), if host1x_device_parse_dt() fails, the current error path frees the object directly with kfree(device). That bypasses the normal device lifetime handling and leaks the reference held on the embedded struct device. The issue was identified by a static analysis tool I developed and confirmed by manual review. Fix this by using put_device() in the host1x_device_parse_dt() failure path.
