- Summary
- CVE-2024-45029 affecting package kernel for versions less than 6.6.51.1-1
- Details
-
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_xferThe problem arises because during _pmruntimeresume(), the spinlock &dev->power.lock is acquired before rpmresume() is called. Later, rpmresume() invokes acpisubsysruntimeresume(), 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 acpisubsysruntime_resume() on mutexes.
