CVE-2026-89674

A flaw in the Linux kernel nfsd component, specifically in the nfsd4_ff_encode_layoutget() function, involves multiple errors in XDR buffer size calculations. The errors cause either an out-of-bounds write (up to 5 bytes past the reserved buffer when short strings like uid=0/gid=0 are combined wi...
