{"id":"CVE-2026-99089","summary":"ASoC: samsung: i2s: enable op_clk in probe to balance runtime PM","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: samsung: i2s: enable op_clk in probe to balance runtime PM\n\nThe probe function puts the device into the runtime PM active state with\nonly the \"iis\" bus clock enabled, but it also sets priv-\u003eop_clk to the\nparent of the RCLK_SRC mux without enabling it. The runtime PM suspend\ncallback disables both clocks, so the first runtime suspend after probe\ndisables op_clk once more than it was enabled.\n\nOn Exynos5250 Arndale both clocks resolve to the same EXYNOS_I2S_BUS gate,\nso this triggers the following warning during boot:\n\n WARNING: drivers/clk/clk.c:1270 at clk_core_disable+0xe4/0x23c, CPU#0: kworker/u8:3/45\n i2s_bus already disabled\n ...\n Workqueue: pm pm_runtime_work\n Call trace:\n  ...\n  clk_core_disable from clk_disable+0x28/0x34\n  clk_disable from i2s_runtime_suspend+0x58/0x68 [snd_soc_i2s]\n  i2s_runtime_suspend [snd_soc_i2s] from genpd_runtime_suspend+0xc4/0x298\n  genpd_runtime_suspend from __rpm_callback+0x48/0x18c\n  __rpm_callback from rpm_callback+0x4c/0x50\n  rpm_callback from rpm_suspend+0xf4/0x718\n  rpm_suspend from pm_runtime_work+0x9c/0xa0\n  ...\n\nFix this by enabling op_clk in probe right after getting it, so the clock\nstate matches the runtime PM active state, and by disabling it in remove.","modified":"2026-11-06T17:27:30.041652899Z","published":"2026-10-26T14:51:59.055Z","related":["SUSE-SU-2026:24550-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99089.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/004c8ec5d71c01b93284042f1174b70cf1390e59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/05d79040b7ebd46862c4bf4864d373dad8b6fecb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/09cda41564966c7f9d2a5fa7022af18b5d4161be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c64c30d493d82d5edc95811cede0083e1195822"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5dac6bf09b5a4fff2433629801309c3884c3e94a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64bb35079dcbc67901da1fe8c52c234cbcd17df3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7529254014764ae0b8c33d5c61a58f36c65b1a1c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a728c12f8bd89947894e227d0f4f83a895ac9ab7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99089.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99089"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"48279c53fd1d09dc0d1b6ebb9f21732c507cea0b"},{"fixed":"09cda41564966c7f9d2a5fa7022af18b5d4161be"},{"fixed":"004c8ec5d71c01b93284042f1174b70cf1390e59"},{"fixed":"05d79040b7ebd46862c4bf4864d373dad8b6fecb"},{"fixed":"2c64c30d493d82d5edc95811cede0083e1195822"},{"fixed":"5dac6bf09b5a4fff2433629801309c3884c3e94a"},{"fixed":"64bb35079dcbc67901da1fe8c52c234cbcd17df3"},{"fixed":"a728c12f8bd89947894e227d0f4f83a895ac9ab7"},{"fixed":"7529254014764ae0b8c33d5c61a58f36c65b1a1c"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99089.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.17.0"},{"fixed":"5.10.273"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99089.json"}}],"schema_version":"1.9.2"}
