Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 6.12.111/6.18.53/7.2.7/7.3-rc3. Affected is the function amdgpu_pci_remove of the component amdgpu. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix rmmio iounmap skipped on device removal amdgpu_pci_remove() calls drm_dev_unplug() before fini_sw(), so drm_dev_enter() is already false there and the iounmap() guarded by it is skipped. This .remove path runs on both hot-unplug and plain rmmod, so the register BAR ioremap mapping leaks one instance per unload. Unmap rmmio unconditionally (guard only on non-NULL) and drop the now unused idx. (cherry picked from commit dd6f86a97260e5207d3329ad03aa89fdad61b1e6)
