CVE-2026-98905: drm/amdkfd: Properly acquire queue buffers in CRIU restore

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 20a5e7ffdfecddc34c60a6b4483f42acf3d8731d, c6c290e408fe328e091f0bf7502a42b0deea82e9, e2dbdd14c3352483a89e4a9afda05d0f3fcc2c83; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 20a5e7ffdfecddc34c60a6b4483f42acf3d8731d, c6c290e408fe328e091f0bf7502a42b0deea82e9, e2dbdd14c3352483a89e4a9afda05d0f3fcc2c83; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Properly acquire queue buffers in CRIU restore When kfd_queue_acquire_buffers() was split off from set_queue_properties_from_user(), set_queue_properties_from_criu() was missed. Thus, set_queue_properties_from_criu() is not filling out the buffer fields of queue_properties, which can come up when subsequent code expects them to be non-null. Add the proper call to kfd_queue_acquire_buffers(), and also use the right cast types in set_queue_properties_from_criu() (which were missed at the same time) (cherry picked from commit 88ed96abbbe27b70193544fbc1ee06448c274714)
