CVE-2026-89703

CVE-2026-89703 is a use-after-free vulnerability in the nfsd component of the Linux kernel. The function nfsd4_drop_revoked_stid() handles FREE_STATEID for admin-revoked delegations but fails to set the SC_STATUS_FREED flag before releasing cl_lock. Without this flag, revoke_delegation() adds the...

CVE-2026-89702

In the Linux kernel, the following vulnerability has been resolved: nfsd: size fhverify server sockaddr slot by xptlocallen The nfsdfhverify and nfsdfhverifyerr tracepoints declare the server sockaddr slot sized by xptremotelen but fill it from xptlocal using xptlocallen: TPSTRUCTentry...

CVE-2026-89702

CVE-2026-89702 is a buffer overflow in the Linux kernel's NFSd (Network File System Daemon). The nfsd_fh_verify and nfsd_fh_verify_err tracepoints declare the server sockaddr ring-buffer slot using xpt_remotelen but fill it from xpt_local using xpt_locallen. For NFSv2/v3-over-UDP connections, xpt...
