CVE-2023-5345

Use-after-free in Linux kernel's fs/smb/client component

A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705.

kernel: drm/virtio: improper return value check in virtio_gpu_object_shmem_init()

In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).

kernel: blocking operation in dvb_frontend_get_event and wait_event_interruptible

An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.
