  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: cx88: Fix a null-ptr-deref bug in buffer_prepare()  When the driver calls cx88_risc_buffer() to prepare the buffer, the function call may fail, resulting in a empty buffer and null-ptr-deref later in buffer_queue().  The following log can reveal it:  [   41.822762] general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN PTI [   41.824488] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] [   41.828027] RIP: 0010:buffer_queue\u002B0xc2/0x500 [   41.836311] Call Trace: [   41.836945]  __enqueue_in_driver\u002B0x141/0x360 [   41.837262]  vb2_start_streaming\u002B0x62/0x4a0 [   41.838216]  vb2_core_streamon\u002B0x1da/0x2c0 [   41.838516]  __vb2_init_fileio\u002B0x981/0xbc0 [   41.839141]  __vb2_perform_fileio\u002B0xbf9/0x1120 [   41.840072]  vb2_fop_read\u002B0x20e/0x400 [   41.840346]  v4l2_read\u002B0x215/0x290 [   41.840603]  vfs_read\u002B0x162/0x4c0  Fix this by checking the return value of cx88_risc_buffer()  [hverkuil: fix coding style issues]",
