In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
mmc: hsq: Fix use-after-free in retry work<\/p>\n
mmc_hsq_pump_requests() queues retry_work when request_atomic() returns
\n-EBUSY; today sdhci-sprd is the only consumer that implements
\nrequest_atomic(). The work is embedded in a devm-allocated mmc_hsq, but
\nis never cancelled during driver removal. Work still pending at unbind
\ncan therefore run after the devm allocation has been released and
\ndereference hsq->mmc and hsq->mrq.<\/p>\n
Use devm_work_autocancel() to cancel and drain retry_work before the devm
\nallocation is released. By the time devres cleanup begins,
\nmmc_remove_host() has already stopped the host, so no new requests can
\narm the work.<\/p>\n
