CVE-2024-45029: i2c: tegra: Do not mark ACPI devices as irq safe

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: 0.17% (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 14d069d92951a3e150c0a81f2ca3b93e54da913b, 2853e1376d8161b04c9ff18ba82b43f08a049905, 6861faf4232e4b78878f2de1ed3ee324ddae2287; Azure Linux 3.0 ARM 6.6.51.1-1; Azure Linux 3.0 x64 6.6.51.1-1.

Low priority for now. Upgrade to Linux Linux 14d069d92951a3e150c0a81f2ca3b93e54da913b, 2853e1376d8161b04c9ff18ba82b43f08a049905, 6861faf4232e4b78878f2de1ed3ee324ddae2287; Azure Linux 3.0 ARM 6.6.51.1-1; Azure Linux 3.0 x64 6.6.51.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: Do not mark ACPI devices as irq safe On ACPI machines, the tegra i2c module encounters an issue due to a mutex being called inside a spinlock. This leads to the following bug: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:585 ... Call trace: __might_sleep __mutex_lock_common mutex_lock_nested acpi_subsys_runtime_resume rpm_resume tegra_i2c_xfer The problem arises because during __pm_runtime_resume(), the spinlock &dev->power.lock is acquired before rpm_resume() is called. Later, rpm_resume() invokes acpi_subsys_runtime_resume(), which relies on mutexes, triggering the error. To address this issue, devices on ACPI are now marked as not IRQ-safe, considering the dependency of acpi_subsys_runtime_resume() on mutexes.
