https://notcve.org/view.php?id=CVE-2024-43868
In the Linux kernel, the following vulnerability has been resolved: riscv/purgatory: align riscv_kernel_entry When alignment handling is delegated to the kernel, everything must be word-aligned in purgatory, since the trap handler is then set to the kexec one. Without the alignment, hitting the exception would ultimately crash. On other occasions, the kernel's handler would take care of exceptions. This has been tested on a JH7110 SoC with oreboot and its SBI delegating unaligned access exceptions and the kernel configured to handle them. • https://git.kernel.org/stable/c/736e30af583fb6e0e2b8211b894ff99dea0f1ee7 https://git.kernel.org/stable/c/5d4aaf16a8255f7c71790e211724ba029609c5ff https://git.kernel.org/stable/c/fb197c5d2fd24b9af3d4697d0cf778645846d6d5 •

https://notcve.org/view.php?id=CVE-2024-43867
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: prime: fix refcount underflow Calling nouveau_bo_ref() on a nouveau_bo without initializing it (and hence the backing ttm_bo) leads to a refcount underflow. Instead of calling nouveau_bo_ref() in the unwind path of drm_gem_object_init(), clean things up manually.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Always drain health in shutdown callback There is no point in recovery during device shutdown. if health work started need to wait for it to avoid races and NULL pointer access.

https://notcve.org/view.php?id=CVE-2024-43864
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix CT entry update leaks of modify header context The cited commit allocates a new modify header to replace the old one when updating CT entry. But if failed to allocate a new one, eg. exceed the max number firmware can support, modify header will be an error pointer that will trigger a panic when deallocating it. And the old modify header point is copied to old attr. When the old attr is freed, the old modify header is lost. Fix it by restoring the old attr to attr when failed to allocate a new modify header context. So when the CT entry is freed, the right modify header context will be freed. • https://git.kernel.org/stable/c/94ceffb48eac7692677d8093dcde6965b70c4b35 https://git.kernel.org/stable/c/daab2cc17b6b6ab158566bba037e9551fd432b59 https://git.kernel.org/stable/c/89064d09c56b44c668509bf793c410484f63f5ad https://git.kernel.org/stable/c/025f2b85a5e5a46df14ecf162c3c80a957a36d0b •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-43863 – drm/vmwgfx: Fix a deadlock in dma buf fence polling
https://notcve.org/view.php?id=CVE-2024-43863
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix a deadlock in dma buf fence polling Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks. vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock. dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called. Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock. • https://git.kernel.org/stable/c/2298e804e96eb3635c39519c8287befd92460303 https://git.kernel.org/stable/c/9e20d028d8d1deb1e7fed18f22ffc01669cf3237 https://git.kernel.org/stable/c/3b933b16c996af8adb6bc1b5748a63dfb41a82bc https://git.kernel.org/stable/c/a8943969f9ead2fd3044fc826140a21622ef830e https://git.kernel.org/stable/c/c98ab18b9f315ff977c2c65d7c71298ef98be8e3 https://git.kernel.org/stable/c/e58337100721f3cc0c7424a18730e4f39844934f •
