However, if the network interface was\nnot previously enabled, the `priv->wq` (workqueue) is not allocated and\ninitialized, leading to a null pointer dereference.\n\nTo fix this, we move the allocation and initialization of the workqueue\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.\nThis ensures that the workqueue is properly initialized before it is\nused during device resume. And added logic to destroy the workqueue\nin the error handling paths of `hi3110_can_probe` and in the\n`hi3110_can_remove` function to prevent resource leaks."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/can/spi/hi311x.c"],"versions":[{"version":"57e83fb9b7468c75cb65cde1d23043553c346c6d","lessThan":"d1fc4c041459e2d4856c1b2501486ba4f0cbf96b","status":"affected","versionType":"git"},{"version":"57e83fb9b7468c75cb65cde1d23043553c346c6d","lessThan":"e93af787187e585933570563c643337fa731584a","status":"affected","versionType":"git"},{"version":"57e83fb9b7468c75cb65cde1d23043553c346c6d","lessThan":"1d2ef21f02baff0c109ad78b9e835fb4acb14533","status":"affected","versionType":"git"},{"version":"57e83fb9b7468c75cb65cde1d23043553c346c6d","lessThan":"fd00cf38fd437c979f0e5905e3ebdfc3f55a4b96","status":"affected","versionType":"git"},{"version":"57e83fb9b7468c75cb65cde1d23043553c346c6d","lessThan":"6b696808472197b77b888f50bc789a3bae077743","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/can/spi/hi311x.c"],"versions":[{"version":"4.12","status":"affected"},{"version":"0","lessThan":"4.12","status":"unaffected","versionType":"semver"},{"version":"6.1.156","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.111","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.52","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.16.12","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.1.156"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.6.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.12.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.16.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d1fc4c041459e2d4856c1b2501486ba4f0cbf96b"},{"url":"https://git.kernel.org/stable/c/e93af787187e585933570563c643337fa731584a"},{"url":"https://git.kernel.org/stable/c/1d2ef21f02baff0c109ad78b9e835fb4acb14533"},{"url":"https://git.kernel.org/stable/c/fd00cf38fd437c979f0e5905e3ebdfc3f55a4b96"},{"url":"https://git.kernel.org/stable/c/6b696808472197b77b888f50bc789a3bae077743"}],"title":"can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled","x_generator":{"engine":"bippy-1.2.0"}}}}
