kernel: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

A flaw was found in the Linux kernel's RDMA/mana component. A local user could trigger a kernel corruption by providing specific configurations through the user Application Programming Interface uAPI that cause an internal error. This issue arises when Work Queues WQs are specified to share the...

CVE-2026-64102

A flaw was found in the Linux kernel's Soft-iWARP siw component for Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted iWARP Fast Path Data Unit FPDU with a manipulated length field. This manipulation causes an integer underflow, leading to a use-after-free...

CVE-2026-64102 RDMA/siw: Reject MPA FPDU length underflow before signed receive math

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Reject MPA FPDU length underflow before signed receive math A malicious connected siw peer can send an iWARP FPDU whose MPA length field chdr-mpalen, 16 bit big-endian, peer-controlled is smaller than the fixed DDP/RDMA...

CVE-2026-64102

CVE-2026-64102 affects the Linux kernel RDMA/siw path. A malicious siw peer can send an iWARP FPDU whose MPA length (mpa_len) is smaller than the fixed DDP/RDMAP header for the announced opcode, triggering an underflow in fpdu_part_rem during siw_tcp_rx_data and leading to a potential out-of-boun...

CVE-2026-64033

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs: Fix use-after-free in path file creation cleanup In the error path of rtrssrvcreatepathfiles, the sysfs root folders may already have been created and srvpath-kobj may already have been initialized. If a later step...

EUVD-2026-45606

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs: Fix use-after-free in path file creation cleanup In the error path of rtrssrvcreatepathfiles, the sysfs root folders may already have been created and srvpath-kobj may already have been initialized. If a later step...

CVE-2026-63860

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Prefer NLANULSTRING These attributes are evaluated as c-string passed to strcmp, but NLASTRING doesn't check for the presence of a \0 terminator. Either this needs to switch to nlastrcmp and needs to adjust printf fmt...

CVE-2026-63860

The CVE-2026-63860 entry affects the Linux kernel RDMA/core code, where attributes are evaluated as C-strings and NLA_STRING does not ensure a terminating null. The vulnerability is addressed by switching to NLA_NUL_STRING (or equivalent safe comparison via nla_strcmp and adjusted printf formatti...

EUVD-2026-45441

In the Linux kernel, the following vulnerability has been resolved: RDMA/ionic: bound nodedesc sysfs read with %.64s nodedesc64 in struct ibdevice is not guaranteed to be NUL- terminated. The core IB sysfs handler uses "%.64s" for exactly this reason drivers/infiniband/core/sysfs.c:1307, since...

CVE-2026-53371

The CVE-2026-53371 issue affects the Linux kernel RDMA/ionic driver. It stems from node_desc not guaranteed to be NUL-terminated when 64 bytes are written to the node_desc sysfs file; the ionic hca_type_show() uses an unbounded %s, reading past node_desc into adjacent ib_device fields. The kernel...

PT-2026-61419
