Description OSIDB Bzimport 2026-07-25 10:08:51 UTC 
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.
