CVE-2022-50181 virtio-gpu: fix a missing check to avoid NULL dereference

In the Linux kernel, the following vulnerability has been resolved: virtio-gpu: fix a missing check to avoid NULL dereference 'cacheent' could be set NULL inside virtiogpucmdgetcapset and it will lead to a NULL dereference by a lately use of it i.e., ptr = cacheent-capscache. Fix it with a NULL...

CVE-2022-50181

CVE-2022-50181 affects the Linux kernel’s virtio-gpu driver. The vulnerability arises from a missing NULL check in virtio_gpu_cmd_get_capset(), where a NULL-ified cache_ent could be dereferenced (ptr = cache_ent->caps_cache). This results in a NULL pointer dereference. The issue has been resol...

CVE-2022-50177 rcutorture: Fix ksoftirqd boosting timing and iteration

In the Linux kernel, the following vulnerability has been resolved: rcutorture: Fix ksoftirqd boosting timing and iteration The RCU priority boosting can fail in two situations: 1 If nrcpus= maxcpus=, which means if the total number of CPUs is higher than those brought online at boot, then...

CVE-2022-50176

In CVE-2022-50176, the Linux kernel’s drm/mcde mcde_dsi_bind had a refcount leak: every iteration of for_each_available_child_of_node() decremented the previous node’s refcount, but a missing of_node_put() on loop exit caused leaks. The fix is to add of_node_put() to restore correct refcount hand...
