CVE-2022-49316 Details
Description
In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open() compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr(). The reason is that those calls could trigger a recall, which could deadlock.
A vulnerability in the Linux kernel's NFSv4 implementation can lead to deadlocks when handling layout get operations. This issue arises because layout locks are held across multiple RPC calls, such as 'setattr()', which can trigger a recall and potentially cause a deadlock. The vulnerability has been addressed by ensuring that layout locks are released before making further RPC calls.
