CVE-2026-89664

CVE-2026-89664 is a memory-leak vulnerability in the Linux kernel NFS daemon (nfsd) . When nfsd4_decode_createhow4() allocates refcounted posix_acl objects for an OPEN compound, they were never released on two code paths: (1) the short-circuit path taken when nfsd4_decode_open_claim4() returns a ...

EUVD-2026-76576

In the Linux kernel, the following vulnerability has been resolved: nfsd: release OPEN-decoded posix ACLs via oprelease nfsd4decodecreatehow4 calls nfsd4decodefattr4, which allocates refcounted struct posixacl objects via posixaclalloc and stores them in open-oppacl and open-opdpacl. These pointe...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfsd: calls oprelease, even when opfunc returns an error. For operations with “trivial” responses, nfsd4encodeoperation will shortcut most of the encoding process and simply perform marshaling of the status. One of the things it...

The vulnerability of the op_release() function in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the oprelease function in the Linux operating system’s kernel is related to the lack of memory release after the effective lifespan has ended. Exploiting this vulnerability can allow an attacker to cause a service failure...
