PT-2026-37623

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ec bhf ethernet driver where the dma free coherent function in the error path incorrectly uses priv-rx buf.alloc len as the DMA handle. This results in the imprope...

kernel: RDMA/rxe: Fix incomplete state save in rxe_requester

An incorrect state restoration flaw was found in the Linux kernel's RDMA rxe soft-RoCE driver in the requester packet transmission logic. A local user with access to RDMA devices can trigger this issue when network layer packet drops occur during RDMA send operations, causing the work queue eleme...

DyMA-Fuzz: Dynamic Direct Memory Access Abstraction for Re-Hosted Monolithic Firmware Fuzzing

The rise of smart devices in critical domains--including automotive, medical, industrial--demands robust firmware testing. Fuzzing firmware in re-hosted environments is a promising method for automated testing at scale, but remains difficult due to the tight coupling of code with a...

RHEL 9 : kernel (RHSA-2026:2352)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:2352 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: sched: schcake: add bounds...

The vulnerability in the vmw_cmd_dma() function of the drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c file, a driver for the Direct Rendering Infrastructure (DRI) of the Linux operating system, allows an attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the vmwcmddma function in the drivers/gpu/drm/vmwgfx/vmwgfxexecbuf.c file of the Direct Rendering Infrastructure DRI driver in the Linux operating system is related to the assignment of pointers. Exploiting this vulnerability could allow an attacker to compromise the...
