CVE-2022-50275 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Add the missed acpi_put_table() to fix memory leak When the radeon driver reads the bios information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak. v2: fix text formatting (Alex)
A memory leak vulnerability has been identified in the Linux kernel's Radeon graphics driver. When the driver retrieves BIOS information from the ACPI VFCT table, it fails to release the allocated ACPI memory by not calling the necessary cleanup function. This oversight can lead to increased memory usage over time. The issue has been addressed by adding the missing function call to properly release the memory, thereby preventing the leak.
Users can upgrade to the patched version of the Linux kernel available in the Linux Kernel Stable Tree to address this vulnerability.
