CVE-2026-93221

The Linux kernel is vulnerable to a race condition in the nfsd component due to a lack of serialization when accessing boolean fields in nfsd_net. Specifically, the nfsd4_end_grace() function uses a plain boolean for grace_ended, allowing concurrent paths—such as the laundromat path and the RECLA...
