https://notcve.org/view.php?id=CVE-2024-41097
In the Linux kernel, the following vulnerability has been resolved: usb: atm: cxacru: fix endpoint checking in cxacru_bind() Syzbot is still reporting quite an old issue [1] that occurs due to incomplete checking of present usb endpoints. As such, wrong endpoints types may be used at urb sumbitting stage which in turn triggers a warning in usb_submit_urb(). Fix the issue by verifying that required endpoint types are present for both in and out endpoints, taking into account cmd endpoint type. Unfortunately, this patch has not been tested on real hardware.

In the past, there were similar failures reported by CI from other IGT tests, observed on other platforms. Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for idleness of vma->active via fence_update(). That commit introduced vma->fence->active in order for the fence_update() to be able to wait selectively on that one instead of vma->active since only idleness of fence registers was needed. But then, another commit 0d86ee35097a ("drm/i915/gt: Make fence revocation unequivocal") replaced the call to fence_update() in i915_vma_revoke_fence() with only fence_write(), and also added that GEM_BUG_ON(! • https://git.kernel.org/stable/c/0d86ee35097ae0f1c2c50f2b8035ef480e25e4f1 https://git.kernel.org/stable/c/f771b91f21c46ad1217328d05e72a2c7e3add535 https://git.kernel.org/stable/c/29c0fdf49078ab161570d3d1c6e13d66f182717d https://git.kernel.org/stable/c/ca0fabd365a27a94a36e68a7a02df8ff3c13dac6 https://git.kernel.org/stable/c/06dec31a0a5112a91f49085e8a8fa1a82296d5c7 https://git.kernel.org/stable/c/414f4a31f7a811008fd9a33b06216b060bad18fc https://git.kernel.org/stable/c/996c3412a06578e9d779a16b9e79ace18125ab50 •
