—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 2f390b4c83011452753fd84972f657d2b00a952b, 51eeef1949c11d3dcb5f422a5d9b3f09ebe8a1bc, 7aea619d9f186dcf0f1289879e9edb69d2b56639.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2f390b4c83011452753fd84972f657d2b00a952b, 51eeef1949c11d3dcb5f422a5d9b3f09ebe8a1bc, 7aea619d9f186dcf0f1289879e9edb69d2b56639 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix bo->pin leaking in amdgpu_bo_create_reserved amdgpu_bo_create_reserved() only allocates a new BO when *bo_ptr (struct amdgpu_bo **bo_ptr as input parameter) is NULL, it simply skips creation when *bo_ptr is non-NULL. But it unconditionally reserves, pins, gart allocates and maps the BO afterwards. When the same non-NULL BO pointer is passed in again, for example firmware buffers that live in adev and are re-loaded on every resume / cp_resume / start under AMDGPU_FW_LOAD_DIRECT, amdgpu_bo_pin() just increases pin_count unconditionally, however the matching teardown only unpins once, so pin_count never drops to zero, so TTM is not able to move, swap or evict a BO, causing BO leaks. This commit fixes this issue by only pinning the bo once at creation, and repeated calls no longer take additional pin references. (cherry picked from commit 3ddc0ae76202c447b6aec61e907b852bc94671cf)
