CVE-2026-68238

A flaw was found in the drm/amdgpu component of the Linux kernel. The amdgpuacpivfctbios function fails to release a reference to the VFCT ACPI table after fetching it. This oversight leads to a resource leak, where memory allocated for the table mapping is not properly freed, potentially impacti...

CVE-2026-68238

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Release VFCT ACPI table reference amdgpuacpivfctbios fetches the VFCT table with acpigettable but never releases it. acpigettable takes a reference on the table incrementing its validationcount and mapping it on the 0...

The vulnerability of the radeon_acpi_vfct_bios() function in the drivers/gpu/drm/radeon/radeon_bios.c driver of the Direct Rendering Infrastructure (DRI) graphics card for Linux operating systems allows a hacker to cause a system failure.

The vulnerability of the radeonacpivfctbios function in the drivers/gpu/drm/radeon/radeonbios.c driver of the Direct Rendering Infrastructure DRI video card for Linux operating systems is related to improper memory release. Exploiting this vulnerability can allow an attacker to cause a system...

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 that stems from a failure to call acpiputtable in the radeonacpivfctbios function to free up ACPI memory, which could lead t...

kernel: drm/radeon: Add the missed acpi_put_table() to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Add the missed acpiputtable to fix memory leak When the radeon driver reads the bios information from ACPI table in radeonacpivfctbios, it misses to call acpiputtable to release the ACPI memory after the init, so add...
