CVE-2026-98155

A flaw was found in the Linux kernel's Qualcomm Cloud AI qaic driver. A compromised or malicious device could trigger a Denial of Service DoS or information disclosure by sending a malformed response message. Due to missing bounds checks during message processing, the driver may read beyond...

The vulnerability of the qaic_gem_object_mmap() function in the drivers/accel/qaic/qaic_data.c file of the Linux kernel’s acceleration device driver allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the qaicgemobjectmmap function in the drivers/accel/qaic/qaicdata.c file of the Linux kernel’s acceleration device driver is related to the execution of operations outside of the buffer boundaries. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-64051

A flaw was found in the Linux kernel's accel/qaic driver. This vulnerability allows for memory to be mapped beyond its intended boundaries during certain memory allocation operations. A local attacker could exploit this flaw, leading to a use-after-free condition. This could potentially result in...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel, which stems from a failure to process a DBC de-activation transaction in the qaic driver after a user leaves, which could...

CVE-2025-40172

CVE-2025-40172 is connected to the Linux kernel’s QAIC driver (drivers/accel/qaic/qaic_control.c). The issue arises in find_and_map_user_pages(): when a DMA transfer request from user space has a length of 0, or in a rare case the host/device signals QAIC_TRANS_DMA_XFER_CONT with resources->xf...
