In the\ncomplete callback usb_8dev_read_bulk_callback(), the URBs are processed and\nresubmitted. In usb_8dev_close() -> unlink_all_urbs() the URBs are freed by\ncalling usb_kill_anchored_urbs(&priv->rx_submitted).\n\nHowever, this does not take into account that the USB framework unanchors\nthe URB before the complete function is called. This means that once an\nin-URB has been completed, it is no longer anchored and is ultimately not\nreleased in usb_kill_anchored_urbs().\n\nFix the memory leak by anchoring the URB in the\nusb_8dev_read_bulk_callback() to the priv->rx_submitted anchor."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/can/usb/usb_8dev.c"],"versions":[{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"feb8243eaea7efd5279b19667d7189fd8654c87a","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"ef6e608e5ee71eca0cd3475c737e684cef24f240","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"60719661b4cbd7ffbed1a0e0fa3bbc82d8bd2be9","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"59ff56992bba28051ad67cd8cc7b0edfe7280796","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"ea4a98e924164586066b39f29bfcc7cc9da108cd","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"07e9373739c6388af9d99797cdb2e79dbbcbe92b","status":"affected","versionType":"git"},{"version":"0024d8ad1639e32d717445c69ca813fd19c2a91c","lessThan":"f7a980b3b8f80fe367f679da376cf76e800f9480","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/usb/usb_8dev.c"],"versions":[{"version":"3.9","status":"affected"},{"version":"0","lessThan":"3.9","status":"unaffected","versionType":"semver"},{"version":"5.10.249","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.199","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.162","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.122","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.68","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.8","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19","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":"3.9","versionEndExcluding":"5.10.249"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"5.15.199"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.1.162"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.6.122"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.12.68"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.18.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.9","versionEndExcluding":"6.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/feb8243eaea7efd5279b19667d7189fd8654c87a"},{"url":"https://git.kernel.org/stable/c/ef6e608e5ee71eca0cd3475c737e684cef24f240"},{"url":"https://git.kernel.org/stable/c/60719661b4cbd7ffbed1a0e0fa3bbc82d8bd2be9"},{"url":"https://git.kernel.org/stable/c/59ff56992bba28051ad67cd8cc7b0edfe7280796"},{"url":"https://git.kernel.org/stable/c/ea4a98e924164586066b39f29bfcc7cc9da108cd"},{"url":"https://git.kernel.org/stable/c/07e9373739c6388af9d99797cdb2e79dbbcbe92b"},{"url":"https://git.kernel.org/stable/c/f7a980b3b8f80fe367f679da376cf76e800f9480"}],"title":"can: usb_8dev: usb_8dev_read_bulk_callback(): fix URB memory leak","x_generator":{"engine":"bippy-1.2.0"}}}}
