CVE-2026-64519: Linux

Описание

Оригинално описание

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.
