CVE-2026-89526

A flaw was found in the svcrdma component of the Linux kernel. A remote attacker can exploit this vulnerability by supplying a crafted RPC/RDMA Read chunk position field that is not properly validated against the received inline body length. This can lead to an underflow, exposing adjacent slab...

CVE-2026-89508

A flaw was found in the Linux kernel's RDMA/ucma component. A race condition exists in the ucmasetibpath function when handling events concurrently with ucmamigrateid. This can allow a local attacker with access to an RDMA device to trigger a use-after-free vulnerability, potentially leading to...

CVE-2026-80983

A flaw was found in the Linux kernel's implementation of the Server Message Block SMB over Remote Direct Memory Access RDMA protocol, specifically within the net/smc component. An error path in the smcswitchconns function, triggered during link failover events, can lead to a socket reference coun...

CVE-2026-89505

A flaw was found in the Linux kernel's RDMA/uverbs component. Malformed input from a provider in the legacy write path can cause the uverbsgethandlerfn function to dereference an uninitialized pointer. This can lead to a system crash, resulting in a denial of service...

CVE-2026-89530

A flaw was found in the Linux kernel's svcrdma component, which handles network communication using Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted network reply that is larger than expected. This can cause the system to write data beyond the intended memory area,...

CVE-2026-89509

A flaw was found in the Linux kernel's RDMA/ionic driver. This vulnerability arises from the driver's incorrect handling of rdmacounter allocations, specifically by not embedding counter driver data as required. This oversight can lead to a NULL pointer dereference when the allocandbind function ...

CVE-2026-89506

A flaw was found in the Linux kernel's RDMA/uverbs component. A missing update to the UVERBSMETHODREGMR ioctl allows a malicious userspace program to trigger a null pointer dereference in specific RDMA drivers mthca, irdma, siw. This can lead to a system crash, resulting in a Denial of Service Do...

CVE-2026-89534

A flaw was found in the Linux kernel's svcrdma module. This vulnerability occurs when the system attempts to handle an RDMA Remote Direct Memory Access address change, and a critical memory allocation fails. This can lead to a 'use-after-free' error, where the system tries to access memory that h...

CVE-2026-89510

A flaw was found in the Linux kernel's RDMA/cxgb4 component. This vulnerability occurs when the c4iwremove function frees a device while its registration work regwork is still pending or actively running. This timing issue can lead to the c4iwregisterdevice function attempting to access memory th...

CVE-2026-89533

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Fix offset arithmetic in readchunkrange svcrdmareadchunkrange walks a Read chunk's segment list to build a sub-range starting at byte offset and spanning length bytes for a Position-Zero or Call chunk. Two arithmetic...

DEBIAN-CVE-2026-89532

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Fix pclforeachsegment for empty chunks When a parsed chunk list contains a chunk whose chsegcount is zero, pclforeachsegment computes its inclusive upper bound as &chunk-chsegmentschsegcount - 1. chsegcount is u32, so th...

DEBIAN-CVE-2026-89534

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Clear sccmid when ADDRCHANGE replacement fails When svcrdmalistenhandler handles RDMACMEVENTADDRCHANGE, it creates a replacement listener cmid and returns 1, telling the CM core to destroy the old one. If the replacement...

AZL-100728 CVE-2026-89526 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Validate Read chunk positions before reconstruction The RPC/RDMA Read chunk position field is supplied by the remote client and stored verbatim in the parsed chunk list. xdrcountreadsegments checks only 4-byte alignment;...

DEBIAN-CVE-2026-89530

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Reject inline replies that overflow the pull-up buffer An RPC-over-RDMA client can request a reply, such as an NFS READ payload, without providing a Write list or a Reply chunk to carry it. When such a reply needs more...

CVE-2026-89529

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Reject oversized Read segments at decode time The RPC/RDMA Read list decoder stores wire-supplied segment lengths without validation. xdrcountreadsegments checks 4-byte alignment for non-zero position values but does not...
