CVE-2026-89674

A flaw was found in the nfsd component of the Linux kernel. Incorrect calculations in the XDR External Data Representation buffer size within the nfsd4ffencodelayoutget function can lead to two critical issues. An attacker could potentially exploit this to write data beyond the intended memory...

CVE-2026-89673

A flaw was found in the Linux kernel's NFS daemon nfsd. A remote attacker could exploit an error in the XDR External Data Representation padding calculation within the ffencodegetdeviceinfo function. This mismatch between reserved and actual data size leads to the leakage of stale reply-page...

CVE-2026-89544

A flaw was found in the Linux kernel's SUNRPC component. Multiple defects in the gssxdecoptionarray XDR option-array decoder's error handling can lead to a NULL dereference, a reference count leak, and a use-after-free vulnerability. An attacker could potentially exploit these issues by providing...
