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.

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.
A flaw was found in the Linux kernel's Network File System Daemon (NFSD). This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by triggering an infinite loop during layout state revocation. The issue occurs because the system repeatedly attempts to revoke a layout state without properly updating its status, leading to the revoker hanging indefinitely.
