Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A issue in the Linux kernel has been identified, specifically in the ath10k module, related to error handling in the
ath10k setup msa resources function. The problem arises because the device node pointer returned by of parse phandle() has its refcount incremented, but of node put() is not consistently called to decrement this refcount when the pointer is no longer needed, particularly in error paths. This inconsistency can lead to a refcount leak.Recommendations
For the affected Linux kernel versions, ensure proper error handling by calling
of node put() on the device node pointer in all paths, including error paths, to prevent refcount leaks. As a temporary workaround, consider reviewing and adjusting the error handling mechanisms in the ath10k setup msa resources function to ensure of node put() is called appropriately.Exploit
