CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-35879 – of: dynamic: Synchronize of_changeset_destroy() with the devlink removals
https://notcve.org/view.php?id=CVE-2024-35879
In the Linux kernel, the following vulnerability has been resolved: of: dynamic: Synchronize of_changeset_destroy() with the devlink removals In the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are destroyed and devlinks are removed. During the step 2, OF nodes are destroyed but __of_changeset_entry_destroy() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ... Indeed, during the devlink removals performed at step 1, the removal itself releasing the device (and the attached of_node) is done by a job queued in a workqueue and so, it is done asynchronously with respect to function calls. When the warning is present, of_node_put() will be called but wrongly too late from the workqueue job. In order to be sure that any ongoing devlink removals are done before the of_node destruction, synchronize the of_changeset_destroy() with the devlink removals. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: of:dynamic: Sincronizar of_changeset_destroy() con las eliminaciones de devlink En la siguiente secuencia: 1) of_platform_depopulate() 2) of_overlay_remove() Durante el paso 1, los dispositivos se destruyen y los devlinks son remoto. • https://git.kernel.org/stable/c/d007150b4e15bfcb8d36cfd88a5645d42e44d383 https://git.kernel.org/stable/c/80dd33cf72d1ab4f0af303f1fa242c6d6c8d328f https://git.kernel.org/stable/c/252c23915546863685ecc68cb3a39e7e80c6c9d4 https://git.kernel.org/stable/c/3127b2ee50c424a96eb3559fbb7b43cf0b111c7a https://git.kernel.org/stable/c/3ee2424107546d882e1ddd75333ca9c32879908c https://git.kernel.org/stable/c/7b6df050c45a1ea158fd50bc32a8e1447dd1e951 https://git.kernel.org/stable/c/801c8b8ec5bfb3519566dff16a5ecd48302fca82 https://git.kernel.org/stable/c/ae6d76e4f06c37a623e357e79d49b1741 •

In the Linux kernel, the following vulnerability has been resolved: of: module: prevent NULL pointer dereference in vsnprintf() In of_modalias(), we can get passed the str and len parameters which would cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr when the length is also 0. Also, we need to filter out the negative values of the len parameter as these will result in a really huge buffer since snprintf() takes size_t parameter while ours is ssize_t...

https://notcve.org/view.php?id=CVE-2024-35875
In the Linux kernel, the following vulnerability has been resolved: x86/coco: Require seeding RNG with RDRAND on CoCo systems There are few uses of CoCo that don't rely on working cryptography and hence a working RNG. ... Many device drivers and platforms have some desire to contribute something to the RNG, and add_device_randomness() is specifically meant for this purpose. Any driver can call it with seed data of any quality, or even garbage quality, and it can only possibly make the quality of the RNG better or have no effect, but can never make it worse. Rather than trying to build something into the core of the RNG, consider the particular CoCo issue just a CoCo issue, and therefore separate it all out into driver (well, arch/platform) code.
