| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm cache: fix flushing uninitialized delayed_work on cache_ctr error\n\nAn unexpected WARN_ON from flush_work() may occur when cache creation\nfails, caused by destroying the uninitialized delayed_work waker in the\nerror path of cache_create(). For example, the warning appears on the\nsuperblock checksum error.\n\nReproduce steps:\n\ndmsetup create cmeta --table \"0 8192 linear /dev/sdc 0\"\ndmsetup create cdata --table \"0 65536 linear /dev/sdc 8192\"\ndmsetup create corig --table \"0 524288 linear /dev/sdc 262144\"\ndd if=/dev/urandom of=/dev/mapper/cmeta bs=4k count=1 oflag=direct\ndmsetup create cache --table \"0 524288 cache /dev/mapper/cmeta \\\n/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0\"\n\nKernel logs:\n\n(snip)\nWARNING: CPU: 0 PID: 84 at kernel/workqueue.c:4178 __flush_work+0x5d4/0x890\n\nFix by pulling out the cancel_delayed_work_sync() from the constructor's\nerror path. This patch doesn't affect the use-after-free fix for\nconcurrent dm_resume and dm_destroy (commit 6a459d8edbdb (\"dm cache: Fix\nUAF in destroy()\")) as cache_dtr is not changed." |
