The timer callback may still be running and can\nrearm itself, resulting in a use-after-free.\n\nUse timer_shutdown_sync() to wait for the callback and prevent further\nrearming. Do this unconditionally because ss_en may be changed after\nthe timer is armed.\n\nMove timer_setup() into init_realtek_cr() so the timer is initialized\nbefore any failure path can invoke the destructor.\n\nFound by static analysis."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/storage/realtek_cr.c"],"versions":[{"version":"e931830bb877e2aad9a1be83506f9bdb26c91e4e","lessThan":"524d4257f741cd95eb85e2817c9c890928fcfef7","status":"affected","versionType":"git"},{"version":"e931830bb877e2aad9a1be83506f9bdb26c91e4e","lessThan":"7c4e2f964c65dea4ea22386799d5fb10ef1e3e54","status":"affected","versionType":"git"},{"version":"e931830bb877e2aad9a1be83506f9bdb26c91e4e","lessThan":"cae9dbba6adae21a04a3bd045e07b489847ff2c6","status":"affected","versionType":"git"},{"version":"e931830bb877e2aad9a1be83506f9bdb26c91e4e","lessThan":"4ffee1aebb0c0ffcda9faffd17834ea9b00d42cc","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/usb/storage/realtek_cr.c"],"versions":[{"version":"3.1","status":"affected"},{"version":"0","lessThan":"3.1","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.51","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.5","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc2","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":"3.1","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.1","versionEndExcluding":"6.18.51"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.1","versionEndExcluding":"7.2.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.1","versionEndExcluding":"7.3-rc2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/524d4257f741cd95eb85e2817c9c890928fcfef7"},{"url":"https://git.kernel.org/stable/c/7c4e2f964c65dea4ea22386799d5fb10ef1e3e54"},{"url":"https://git.kernel.org/stable/c/cae9dbba6adae21a04a3bd045e07b489847ff2c6"},{"url":"https://git.kernel.org/stable/c/4ffee1aebb0c0ffcda9faffd17834ea9b00d42cc"}],"title":"usb: storage: realtek_cr: fix use-after-free on disconnect","x_generator":{"engine":"bippy-1.2.0"}}}}
