kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: nvmet: moving async event work off nvmet-wq For the target function nvmetctrlfree, the variable ctrl-asynceventwork is flushed.

CVE-2026-31491

A flaw was found in the Linux kernel's RDMA/irdma component. A local attacker could exploit an integer overflow and truncation vulnerability when the operating system passes a maximum unsigned 32-bit integer U32MAX for SQ/RQ/SRQ size. This can lead to the system incorrectly reporting a successful...

CVE-2026-31493

A flaw was found in the Linux kernel's RDMA/efa component. When an admin command completes with an error during admin queue completion handling, the system attempts to print data from a completion context that has already been freed. This use-after-free vulnerability can lead to the disclosure of...

CVE-2026-31493

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix use of completion ctx after free On admin queue completion handling, if the admin command completed with error we print data from the completion context. The issue is that we already freed the completion context in...

CVE-2026-31491 RDMA/irdma: Harden depth calculation functions

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Harden depth calculation functions An issue was exposed where OS can pass in U32MAX for SQ/RQ/SRQ size. This can cause integer overflow and truncation of SQ/RQ/SRQ depth returning a success when it should have failed...
