{"id":"AZL-111122","summary":"CVE-2026-99089 affecting package kernel 6.6.157.1-1","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":"2026-10-27T14:18:01.057620427Z","published":"2026-10-26T15:16:47Z","upstream":["CVE-2026-99089"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99089"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-111122.json"}}],"schema_version":"1.9.2"}
