In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Fix memory leak in msm_mdss_parse_data_bus_icc_path of_icc_get() alloc resources for path1, we should release it when not need anymore. Early return when IS_ERR_OR_NULL(path0) may leak path1. Defer getting path1 to fix this.

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 •

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.
