Title
media: vsp1: Replace vb2_is_streaming() with vb2_start_streaming_called()
Summary
In the Linux kernel, the following vulnerability has been resolved: media: vsp1: Replace vb2_is_streaming() with vb2_start_streaming_called() The vsp1 driver uses the vb2_is_streaming() function in its .buf_queue() handler to check if the .start_streaming() operation has been called, and decide whether to just add the buffer to an internal queue, or also trigger a hardware run. vb2_is_streaming() relies on the vb2_queue structure's streaming field, which used to be set only after calling the .start_streaming() operation. Commit a10b21532574 ("media: vb2: add (un)prepare_streaming queue ops") changed this, setting the .streaming field in vb2_core_streamon() before enqueuing buffers to the driver and calling .start_streaming(). This broke the vsp1 driver which now believes that .start_streaming() has been called when it hasn't, leading to a crash: [ 881.058705] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 [ 881.067495] Mem abort info: [ 881.070290] ESR = 0x0000000096000006 [ 881.074042] EC = 0x25: DABT (current EL), IL = 32 bits [ 881.079358] SET = 0, FnV = 0 [ 881.082414] EA = 0, S1PTW = 0 [ 881.085558] FSC = 0x06: level 2 translation fault [ 881.090439] Data abort info: [ 881.093320] ISV = 0, ISS = 0x00000006 [ 881.097157] CM = 0, WnR = 0 [ 881.100126] user pgtable: 4k pages, 48-bit VAs, pgdp=000000004fa51000 [ 881.106573] [0000000000000020] pgd=080000004f36e003, p4d=080000004f36e003, pud=080000004f7ec003, pmd=0000000000000000 [ 881.117217] Internal error: Oops: 0000000096000006 [#1] PREEMPT SMP [ 881.123494] Modules linked in: rcar_fdp1 v4l2_mem2mem [ 881.128572] CPU: 0 PID: 1271 Comm: yavta Tainted: G B 6.2.0-rc1-00023-g6c94e2e99343 #556 [ 881.138061] Hardware name: Renesas Salvator-X 2nd version board based on r8a77965 (DT) [ 881.145981] pstate: 400000c5 (nZcv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 881.152951] pc : vsp1_dl_list_add_body+0xa8/0xe0 [ 881.157580] lr : vsp1_dl_list_add_body+0x34/0xe0 [ 881.162206] sp : ffff80000c267710 [ 881.165522] x29: ffff80000c267710 x28: ffff000010938ae8 x27: ffff000013a8dd98 [ 881.172683] x26: ffff000010938098 x25: ffff000013a8dc00 x24: ffff000010ed6ba8 [ 881.179841] x23: ffff00000faa4000 x22: 0000000000000000 x21: 0000000000000020 [ 881.186998] x20: ffff00000faa4000 x19: 0000000000000000 x18: 0000000000000000 [ 881.194154] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [ 881.201309] x14: 0000000000000000 x13: 746e696174206c65 x12: ffff70000157043d [ 881.208465] x11: 1ffff0000157043c x10: ffff70000157043c x9 : dfff800000000000 [ 881.215622] x8 : ffff80000ab821e7 x7 : 00008ffffea8fbc4 x6 : 0000000000000001 [ 881.222779] x5 : ffff80000ab821e0 x4 : ffff70000157043d x3 : 0000000000000020 [ 881.229936] x2 : 0000000000000020 x1 : ffff00000e4f6400 x0 : 0000000000000000 [ 881.237092] Call trace: [ 881.239542] vsp1_dl_list_add_body+0xa8/0xe0 [ 881.243822] vsp1_video_pipeline_run+0x270/0x2a0 [ 881.248449] vsp1_video_buffer_queue+0x1c0/0x1d0 [ 881.253076] __enqueue_in_driver+0xbc/0x260 [ 881.257269] vb2_start_streaming+0x48/0x200 [ 881.261461] vb2_core_streamon+0x13c/0x280 [ 881.265565] vb2_streamon+0x3c/0x90 [ 881.269064] vsp1_video_streamon+0x2fc/0x3e0 [ 881.273344] v4l_streamon+0x50/0x70 [ 881.276844] __video_do_ioctl+0x2bc/0x5d0 [ 881.280861] video_usercopy+0x2a8/0xc80 [ 881.284704] video_ioctl2+0x20/0x40 [ 881.288201] v4l2_ioctl+0xa4/0xc0 [ 881.291525] __arm64_sys_ioctl+0xe8/0x110 [ 881.295543] invoke_syscall+0x68/0x190 [ 881.299303] el0_svc_common.constprop.0+0x88/0x170 [ 881.304105] do_el0_svc+0x4c/0xf0 [ 881.307430] el0_svc+0x4c/0xa0 [ 881.310494] el0t_64_sync_handler+0xbc/0x140 [ 881.314773] el0t_64_sync+0x190/0x194 [ 881.318450] Code: d50323bf d65f03c0 91008263 f9800071 (885f7c60) [ 881.324551] ---[ end trace 0000000000000000 ]--- [ 881.329173] note: yavta[1271] exited with preempt_count 1 A different r ---truncated---

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
