—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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 18b7d69dabb61551d3a45be6300b0e6e6b04d02c, 2aee72150b0ea92804f0f2799efb129f10e46e8d, 3a86ebf6aa8b0a845e6188daaa6f530fe67ff00e; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.159.1-1 on Azure Linux 3.0 6.6.161.1-1.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx6: fix firmware leak on teardown The firmware requested in gfx_v6_0_init_microcode() is not released when the GFX block is torn down, leaking the firmware resources. Add gfx_v6_0_free_microcode() and call it from gfx_v6_0_sw_fini() to release the PFP, ME, CE and RLC firmware. (cherry picked from commit 386e81346f95ab0be5a82c5535de932e7a456924)
