Title
ASoC: samsung: i2s: enable op_clk in probe to balance runtime PM
Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: samsung: i2s: enable op_clk in probe to balance runtime PM The probe function puts the device into the runtime PM active state with only the "iis" bus clock enabled, but it also sets priv->op_clk to the parent of the RCLK_SRC mux without enabling it. The runtime PM suspend callback disables both clocks, so the first runtime suspend after probe disables op_clk once more than it was enabled. On Exynos5250 Arndale both clocks resolve to the same EXYNOS_I2S_BUS gate, so this triggers the following warning during boot: WARNING: drivers/clk/clk.c:1270 at clk_core_disable+0xe4/0x23c, CPU#0: kworker/u8:3/45 i2s_bus already disabled ... Workqueue: pm pm_runtime_work Call trace: ... clk_core_disable from clk_disable+0x28/0x34 clk_disable from i2s_runtime_suspend+0x58/0x68 [snd_soc_i2s] i2s_runtime_suspend [snd_soc_i2s] from genpd_runtime_suspend+0xc4/0x298 genpd_runtime_suspend from __rpm_callback+0x48/0x18c __rpm_callback from rpm_callback+0x4c/0x50 rpm_callback from rpm_suspend+0xf4/0x718 rpm_suspend from pm_runtime_work+0x9c/0xa0 ... Fix this by enabling op_clk in probe right after getting it, so the clock state matches the runtime PM active state, and by disabling it in remove.

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.

Author Source Type Date Other

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.
