Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the
tegra qspi combined seq xfer() function related to the curr xfer field. Specifically, the curr xfer field can be accessed by an interrupt request handler without proper locking, creating a race condition. This race condition occurs when clearing curr xfer within the combined sequence transfer loop and at the exit path of the function. Without adequate protection, the interrupt handler may read a partially updated or invalid curr xfer value, potentially leading to a NULL pointer dereference or a use-after-free condition.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
