Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 5.17.1. Affected by this issue is the function VB2_BUF_STATE_QUEUED of the file drivers/media/common/videobuf2/videobuf2-core.c. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUED If the callback 'start_streaming' fails, then all queued buffers in the driver should be returned with state 'VB2_BUF_STATE_QUEUED'. Currently, they are returned with 'VB2_BUF_STATE_ERROR' which is wrong. Fix this. This also fixes the warning: [ 65.583633] WARNING: CPU: 5 PID: 593 at drivers/media/common/videobuf2/videobuf2-core.c:1612 vb2_start_streaming+0xd4/0x160 [videobuf2_common] [ 65.585027] Modules linked in: snd_usb_audio snd_hwdep snd_usbmidi_lib snd_rawmidi snd_soc_hdmi_codec dw_hdmi_i2s_audio saa7115 stk1160 videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_common videodev mc crct10dif_ce panfrost snd_soc_simple_card snd_soc_audio_graph_card snd_soc_spdif_tx snd_soc_simple_card_utils gpu_sched phy_rockchip_pcie snd_soc_rockchip_i2s rockchipdrm analogix_dp dw_mipi_dsi dw_hdmi cec drm_kms_helper drm rtc_rk808 rockchip_saradc industrialio_triggered_buffer kfifo_buf rockchip_thermal pcie_rockchip_host ip_tables x_tables ipv6 [ 65.589383] CPU: 5 PID: 593 Comm: v4l2src0:src Tainted: G W 5.16.0-rc4-62408-g32447129cb30-dirty #14 [ 65.590293] Hardware name: Radxa ROCK Pi 4B (DT) [ 65.590696] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 65.591304] pc : vb2_start_streaming+0xd4/0x160 [videobuf2_common] [ 65.591850] lr : vb2_start_streaming+0x6c/0x160 [videobuf2_common] [ 65.592395] sp : ffff800012bc3ad0 [ 65.592685] x29: ffff800012bc3ad0 x28: 0000000000000000 x27: ffff800012bc3cd8 [ 65.593312] x26: 0000000000000000 x25: ffff00000d8a7800 x24: 0000000040045612 [ 65.593938] x23: ffff800011323000 x22: ffff800012bc3cd8 x21: ffff00000908a8b0 [ 65.594562] x20: ffff00000908a8c8 x19: 00000000fffffff4 x18: ffffffffffffffff [ 65.595188] x17: 000000040044ffff x16: 00400034b5503510 x15: ffff800011323f78 [ 65.595813] x14: ffff000013163886 x13: ffff000013163885 x12: 00000000000002ce [ 65.596439] x11: 0000000000000028 x10: 0000000000000001 x9 : 0000000000000228 [ 65.597064] x8 : 0101010101010101 x7 : 7f7f7f7f7f7f7f7f x6 : fefefeff726c5e78 [ 65.597690] x5 : ffff800012bc3990 x4 : 0000000000000000 x3 : ffff000009a34880 [ 65.598315] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff000007cd99f0 [ 65.598940] Call trace: [ 65.599155] vb2_start_streaming+0xd4/0x160 [videobuf2_common] [ 65.599672] vb2_core_streamon+0x17c/0x1a8 [videobuf2_common] [ 65.600179] vb2_streamon+0x54/0x88 [videobuf2_v4l2] [ 65.600619] vb2_ioctl_streamon+0x54/0x60 [videobuf2_v4l2] [ 65.601103] v4l_streamon+0x3c/0x50 [videodev] [ 65.601521] __video_do_ioctl+0x1a4/0x428 [videodev] [ 65.601977] video_usercopy+0x320/0x828 [videodev] [ 65.602419] video_ioctl2+0x3c/0x58 [videodev] [ 65.602830] v4l2_ioctl+0x60/0x90 [videodev] [ 65.603227] __arm64_sys_ioctl+0xa8/0xe0 [ 65.603576] invoke_syscall+0x54/0x118 [ 65.603911] el0_svc_common.constprop.3+0x84/0x100 [ 65.604332] do_el0_svc+0x34/0xa0 [ 65.604625] el0_svc+0x1c/0x50 [ 65.604897] el0t_64_sync_handler+0x88/0xb0 [ 65.605264] el0t_64_sync+0x16c/0x170 [ 65.605587] ---[ end trace 578e0ba07742170d ]---
