Astra Linux – Vulnerability in Qemu

An integer overflow was detected in the QEMU implementation of VMWare’s paravirtual RDMA device in versions prior to 6.1.0. The issue occurs when handling a “PVRDMAREGDSRHIGH” write from the guest due to improper input validation. This flaw allows a privileged guest user to instruct QEMU to...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/rxe: Fixed the “kernel NULL pointer dereference” error. When the rxequeueinit function in the rxeqpinitreq function fails, both qp-req.task.func and qp-req.task.arg are not initialized. Due to the failure in creating the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/cma: Fixed a kmemleak in rdmacore that was observed during the blktests nvme/rdma tests with siw. When running the blktests nvme/rdma tests, the following kmemleak issue will appear: - kmemleak: The kernel memory leak...

Astra Linux – Vulnerability in Linux 6.1

A vulnerability was discovered in comparenetdevandip in drivers/infiniband/core/cma.c within RDMA in the Linux kernel. Improper cleanup leads to out-of-boundary reads, allowing a local user to exploit this issue to crash the system or escalate privileges...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxtre: Prevents handling of any completions after the QP Queue Pairing is destroyed. The hardware may generate completions that indicate the QP has been destroyed. The driver should not schedule any completion handlers for...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/srpt: Do not register the event handler until the srpt device is fully set up. In rare cases, KASAN reports a use-after-free error in the srptrefreshport function. This appears to occur because the event handler is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/erdma: Fixed a reference count leak in erdmammap. The function rdmausermmapentryget takes a reference; we should release that reference when it is no longer needed. Add the missing rdmausermmapEntryPut function in the err...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/efa: Fixed the issue of using the completion context after it has been freed. Regarding the handling of admin queue completions, if the admin command completes with an error, we print data from the completion context. The...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/core: Set the send and receive CQ pointers before forwarding them to the driver. Preset both receive and send CQ pointers prior to calling the drivers, and overwrite them again until the mlx4 is changed. Do not overwrite...

Astra Linux – Vulnerability in Linux 5.10

A flaw in the Linux kernel’s implementation of the RDMA communication manager listener code allowed an attacker with local access to set up a socket to listen on a high port. This allowed for a memory element to be used after it was freed. With the ability to execute code, a local attacker could...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: i40e: Fix kernel crash during module removal The driver incorrectly frees client instance and subsequent i40e module removal leads to kernel crash. Reproducer: 1. Do ethtool offline test followed immediately by another one host...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed unsafe code that drained send or recv work queues before they were actually created. If the createqp function does not succeed completely, it is possible for the qp cleanup code to attempt to drain the send or rec...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed an issue where incomplete state saving occurred in rxerequester. If a send packet is dropped by the IP layer in rxerequester, the call to rxexmitpacket may fail with an error code of -EAGAIN. To recover from this...
