https://notcve.org/view.php?id=CVE-2022-48887
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Remove rcu locks from user resources User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two different threads. Because the lookups never show up in performance profiles replace them with a regular spin lock which fixes the races in accesses to those shared resources. Fixes kernel oops'es in IGT's vmwgfx execution_buffer stress test and seen crashes with apps using shared resources. • https://git.kernel.org/stable/c/e14c02e6b6990e9f6ee18a214a22ac26bae1b25e https://git.kernel.org/stable/c/7ac9578e45b20e3f3c0c8eb71f5417a499a7226a https://git.kernel.org/stable/c/a309c7194e8a2f8bd4539b9449917913f6c2cd50 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2022-48884 – net/mlx5: Fix command stats access after free
https://notcve.org/view.php?id=CVE-2022-48884
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix command stats access after free Command may fail while driver is reloading and can't accept FW commands till command interface is reinitialized. Such command failure is being logged to command stats. This results in NULL pointer access as command stats structure is being freed and reallocated during mlx5 devlink reload (see kernel log below). Fix it by making command stats statically allocated on driver probe.

https://notcve.org/view.php?id=CVE-2022-48883
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: IPoIB, Block PKEY interfaces with less rx queues than parent A user is able to configure an arbitrary number of rx queues when creating an interface via netlink. This doesn't work for child PKEY interfaces because the child interface uses the parent receive channels. Although the child shares the parent's receive channels, the number of rx queues is important for the channel_stats array: the parent's rx channel index is used to access the child's channel_stats. So the array has to be at least as large as the parent's rx queue size for the counting to work correctly and to prevent out of bound accesses. This patch checks for the mentioned scenario and returns an error when trying to create the interface. The error is propagated to the user. • https://git.kernel.org/stable/c/be98737a4faa3a0dc1781ced5bbf5c47865e29d7 https://git.kernel.org/stable/c/5844a46f09f768da866d6b0ffbf1a9073266bf24 https://git.kernel.org/stable/c/31c70bfe58ef09fe36327ddcced9143a16e9e83d •
