{"id":"CVE-2026-23108","summary":"can: usb_8dev: usb_8dev_read_bulk_callback(): fix URB memory leak","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: usb_8dev: usb_8dev_read_bulk_callback(): fix URB memory leak\n\nFix similar memory leak as in commit 7352e1d5932a (\"can: gs_usb:\ngs_usb_receive_bulk_callback(): fix URB memory leak\").\n\nIn usb_8dev_open() -\u003e usb_8dev_start(), the URBs for USB-in transfers are\nallocated, added to the priv-\u003erx_submitted anchor and submitted. In the\ncomplete callback usb_8dev_read_bulk_callback(), the URBs are processed and\nresubmitted. In usb_8dev_close() -\u003e unlink_all_urbs() the URBs are freed by\ncalling usb_kill_anchored_urbs(&priv-\u003erx_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-\u003erx_submitted anchor.","modified":"2026-04-02T17:29:25.877616Z","published":"2026-02-04T16:08:28.650Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23108.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07e9373739c6388af9d99797cdb2e79dbbcbe92b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/59ff56992bba28051ad67cd8cc7b0edfe7280796"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60719661b4cbd7ffbed1a0e0fa3bbc82d8bd2be9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ea4a98e924164586066b39f29bfcc7cc9da108cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef6e608e5ee71eca0cd3475c737e684cef24f240"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7a980b3b8f80fe367f679da376cf76e800f9480"},{"type":"WEB","url":"https://git.kernel.org/stable/c/feb8243eaea7efd5279b19667d7189fd8654c87a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23108.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23108"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0024d8ad1639e32d717445c69ca813fd19c2a91c"},{"fixed":"feb8243eaea7efd5279b19667d7189fd8654c87a"},{"fixed":"ef6e608e5ee71eca0cd3475c737e684cef24f240"},{"fixed":"60719661b4cbd7ffbed1a0e0fa3bbc82d8bd2be9"},{"fixed":"59ff56992bba28051ad67cd8cc7b0edfe7280796"},{"fixed":"ea4a98e924164586066b39f29bfcc7cc9da108cd"},{"fixed":"07e9373739c6388af9d99797cdb2e79dbbcbe92b"},{"fixed":"f7a980b3b8f80fe367f679da376cf76e800f9480"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23108.json"}}],"schema_version":"1.7.5"}
