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.\n\n## Affected\n\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < e3da77bdb4015051656bb472c295656bbea03b6f`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < 470fe15fb3bb2eba6629be301ca7e991ee3cfb7e`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < a8a1f9ac3d763e721586f15479ef9140b216ddf3`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < 753060f2b77ff2f386addbd3ecadb95b9f90cddd`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < affd62f5719a78135b7441aa49c8cab3c3b5e838`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < dab4762ee7f3fd0a01980d5407ba48d0261d3bff`\n- `Linux >= f7414cd6923fd7f78e57086fc964ba2dc25db5c1 < 6ac7702b6cc2b94aaed9ef2d95bfbefcdc90061f`\n- `Linux 5.11`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":46.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
