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->slave 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.","state":0,"publishedAt":"2026-08-15T12:27:01.924+00:00","modifiedAt":"2026-10-16T19:05:47.029+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/i2c/busses/i2c-imx.c\"\n ],\n \"versions\": [\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"e3da77bdb4015051656bb472c295656bbea03b6f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"470fe15fb3bb2eba6629be301ca7e991ee3cfb7e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"a8a1f9ac3d763e721586f15479ef9140b216ddf3\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"753060f2b77ff2f386addbd3ecadb95b9f90cddd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"affd62f5719a78135b7441aa49c8cab3c3b5e838\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"dab4762ee7f3fd0a01980d5407ba48d0261d3bff\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"f7414cd6923fd7f78e57086fc964ba2dc25db5c1\",\n \"lessThan\": \"6ac7702b6cc2b94aaed9ef2d95bfbefcdc90061f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/i2c/busses/i2c-imx.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.11\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.11\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.216\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.183\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.151\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.103\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.44\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.8\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/e3da77bdb4015051656bb472c295656bbea03b6f","https://git.kernel.org/stable/c/470fe15fb3bb2eba6629be301ca7e991ee3cfb7e","https://git.kernel.org/stable/c/a8a1f9ac3d763e721586f15479ef9140b216ddf3","https://git.kernel.org/stable/c/753060f2b77ff2f386addbd3ecadb95b9f90cddd","https://git.kernel.org/stable/c/affd62f5719a78135b7441aa49c8cab3c3b5e838","https://git.kernel.org/stable/c/dab4762ee7f3fd0a01980d5407ba48d0261d3bff","https://git.kernel.org/stable/c/6ac7702b6cc2b94aaed9ef2d95bfbefcdc90061f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-74461","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-74461","identifiers":["CVE-2026-74461"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
