{"apiVersion":"1.0","identifier":"CVE-2026-99089","description":"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.","publishedAt":"2026-10-26T15:16:47","lastModifiedAt":"2026-10-30T13:21:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99089","cvssScore":null,"cvssVector":null,"epssProbability":0.00172,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99089","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99089","en":"https://www.redsauce.net/en/cves/CVE-2026-99089","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99089","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99089","de":"https://www.redsauce.net/de/cves/CVE-2026-99089","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99089","el":"https://www.redsauce.net/el/cves/CVE-2026-99089"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99089"}}
