Overview
CVE-2026-64519 is a known-severity vulnerability. It was published on July 25, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix infinite loop in layout state revocation
find_one_sb_stid() skips stids whose sc_status is non-zero, but the
SC_TYPE_LAYOUT case in nfsd4_revoke_states() never sets sc_status
before calling nfsd4_close_layout(). The retry loop therefore finds
the same layout stid on every iteration, hanging the revoker
indefinitely.
