Linux RPC Protocol Heap Buffer Overflow DoS

The vulnerability of the rpcrdmapostrecvs function in the net/sunrpc/xprtrdma/verbs.c module of the Linux operating system’s RPC protocol implementation is related to incorrect resource initialization. Exploiting this vulnerability could allow a malicious actor to cause service failures remotely...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: The pin mechanism for the upper rpcclnt across the TLS-connected connectworker.

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: In the bound-check xdrbuftobvec function, the data is stored before being written. The xdrbuftobvec function writes a biovec into the caller’s array before checking whether that slot is within range. The head branch...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sunrpc: The lifecycle of rqprocinfo has been hardened to prevent double-free operations. The svcreleaserqst function executes the callback within rqstp-rqprocinfo-pcrelease. However, if a worker thread begins processing a new...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fixed the loop termination condition in gssfreeintokenpages. The intoken-pages array is not NULL-terminated. This results in the following KASAN issue: KASAN: Potential wild-memory-access in the range...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: sunrpc: pin svcxprt during the asynchronous TLS handshake callback svctcphandshake stores the raw svcxprt pointer in tlshandshakeargs.tadata and submits the request through tlsserverhellox509. The handshake core only takes...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sunrpc: When canceling a TLS handshake that is still in progress, there is a race condition where the callback for the ongoing handshake is not properly handled. When waitforcompletioninterruptibletimeout in svctcphandshake retur...

SUSE CVE-2026-72317

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: pin upper rpcclnt across the TLS connectworker The TLS connect path has a use-after-free: nothing pins the upper rpcclnt across the delayed connectworker. xsconnect stores task-tkclient in sockxprt::clnt as a raw pointer...

SUSE CVE-2026-72217

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Bound-check xdrbuftobvec stores before writing xdrbuftobvec writes a biovec into the caller's array before testing whether that slot is in range, and the head branch performs the store with no check at all. When the...

SUSE CVE-2026-72220

In the Linux kernel, the following vulnerability has been resolved: sunrpc: harden rqprocinfo lifecycle to prevent double-free The svcreleaserqst function executes the callback inside rqstp-rqprocinfo-pcrelease. However, if a worker thread begins processing a new request and encounters an early...

SUSE CVE-2026-72221

In the Linux kernel, the following vulnerability has been resolved: sunrpc: wait for in-flight TLS handshake callback when cancel loses race When waitforcompletioninterruptibletimeout in svctcphandshake returns 0 timeout or -ERESTARTSYS signal and tlshandshakecancel then returns false,...

SUSE CVE-2026-72222

CVE-2026-72317

A flaw was found in the Linux kernel's SUN Remote Procedure Call SUNRPC implementation. A use-after-free vulnerability exists in the Transport Layer Security TLS connection path. When a TLS handshake fails, the client resource can be prematurely freed, leading to a subsequent attempt to access th...

CVE-2026-72222

A flaw was found in the Linux kernel's sunrpc component, which affects TLS-enabled Network File System NFS servers. A race condition exists during the asynchronous TLS handshake process. A remote attacker could exploit this by closing a connection at a specific time, leading to memory corruption...

CVE-2026-72221

A flaw was found in the kernel. A race condition exists in the sunrpc component during the Transport Layer Security TLS handshake cancellation process. This can lead to the corruption of an internal data structure, potentially causing system instability or a denial of service. Additionally, it ma...

CVE-2026-72217

A flaw was found in the Linux kernel's SUNRPC component. The xdrbuftobvec function performs an out-of-bounds write when processing client-supplied RPC Remote Procedure Call payload sizes without proper boundary checks. A remote attacker could exploit this by crafting malicious RPC requests, leadi...
