{"id":"AZL-96147","summary":"CVE-2026-74461 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: imx: Cancel hrtimer before clearing slave pointer\n\nIn i2c_imx_unreg_slave(), the slave pointer is set to NULL after\ndisabling interrupts.  However, a pending interrupt might already\nhave started the hrtimer (i2c_imx_slave_timeout) before the pointer\nwas cleared.  If the hrtimer fires after i2c_imx-\u003eslave is set to\nNULL, the timer callback i2c_imx_slave_finish_op() will call\ni2c_imx_slave_event() with a NULL slave pointer, which results in a\nuse-after-free / NULL pointer dereference.\n\nFix by canceling the hrtimer and waiting for it to complete after\ndisabling interrupts, before clearing the slave pointer.","modified":"2026-08-30T05:26:50Z","published":"2026-08-15T13:17:50Z","upstream":["CVE-2026-74461"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74461"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96147.json"}}],"schema_version":"1.9.0"}
