No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.10.137
Description
A problem has been identified in the Linux kernel where a sleeping function is called from an invalid context. This issue occurs when the
console lock() function is called while holding a spinlock, which can lead to a bug. The problem is caused by the gsmld write() function taking a spinlock on TX data and then calling con write(), which in turn calls console lock(). Since console lock() might sleep, it should not be called with a spinlock held. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.Recommendations
To resolve this issue, update the Linux kernel to a version that includes the patch replacing the
tx lock spinlock with a mutex.
At the moment, there is no information about a newer version that contains a fix for this vulnerability. Found an issue in the description? Have something to add? Feel free to write us 👾
