Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the nfsd component where certain operations, such as SETATTR, can trigger idmap lookup upcalls during v4 request compound argument decoding. If these upcall responses...

EUVD-2025-203711

In the Linux kernel, the following vulnerability has been resolved: nfs4setupreaddir: insufficient locking for -dparent-dinode dereferencing Theoretically it's an oopsable race, but I don't believe one can manage to hit it on real hardware; might become doable on a KVM, but it still won't be easy...
