{"id":"CVE-2023-52907","summary":"nfc: pn533: Wait for out_urb's completion in pn533_usb_send_frame()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: pn533: Wait for out_urb's completion in pn533_usb_send_frame()\n\nFix a use-after-free that occurs in hcd when in_urb sent from\npn533_usb_send_frame() is completed earlier than out_urb. Its callback\nfrees the skb data in pn533_send_async_complete() that is used as a\ntransfer buffer of out_urb. Wait before sending in_urb until the\ncallback of out_urb is called. To modify the callback of out_urb alone,\nseparate the complete function of out_urb and ack_urb.\n\nFound by a modified version of syzkaller.\n\nBUG: KASAN: use-after-free in dummy_timer\nCall Trace:\n memcpy (mm/kasan/shadow.c:65)\n dummy_perform_transfer (drivers/usb/gadget/udc/dummy_hcd.c:1352)\n transfer (drivers/usb/gadget/udc/dummy_hcd.c:1453)\n dummy_timer (drivers/usb/gadget/udc/dummy_hcd.c:1972)\n arch_static_branch (arch/x86/include/asm/jump_label.h:27)\n static_key_false (include/linux/jump_label.h:207)\n timer_expire_exit (include/trace/events/timer.h:127)\n call_timer_fn (kernel/time/timer.c:1475)\n expire_timers (kernel/time/timer.c:1519)\n __run_timers (kernel/time/timer.c:1790)\n run_timer_softirq (kernel/time/timer.c:1803)","modified":"2026-04-11T12:46:38.201798Z","published":"2024-08-21T06:10:48.171Z","related":["SUSE-SU-2024:3189-1","SUSE-SU-2024:3190-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3227-1","SUSE-SU-2024:3251-1","SUSE-SU-2024:3252-1","SUSE-SU-2024:3408-1","SUSE-SU-2024:3483-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52907.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0ca78c99656f5c448567db1e148367aa3b01c80a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/321db5131c92983dac4f3338e8fbb6df214238c0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/35529d6b827eedb6bf7e81130e4b7e0aba9e58d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39ae73e581112cfe27ba50aecb1c891ce57cecb1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8998db5021a28ad67aa8d627bdb4226e4046ccc4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9424d2205fe94a095fb9365ec0c6137f0b394a2b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9dab880d675b9d0dd56c6428e4e8352a3339371d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52907.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52907"},{"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":"c46ee38620a2aa2b25b16bc9738ace80dbff76a4"},{"fixed":"35529d6b827eedb6bf7e81130e4b7e0aba9e58d2"},{"fixed":"321db5131c92983dac4f3338e8fbb6df214238c0"},{"fixed":"9424d2205fe94a095fb9365ec0c6137f0b394a2b"},{"fixed":"0ca78c99656f5c448567db1e148367aa3b01c80a"},{"fixed":"39ae73e581112cfe27ba50aecb1c891ce57cecb1"},{"fixed":"8998db5021a28ad67aa8d627bdb4226e4046ccc4"},{"fixed":"9dab880d675b9d0dd56c6428e4e8352a3339371d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52907.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1.0"},{"fixed":"4.14.303"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.229"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.164"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.89"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52907.json"}}],"schema_version":"1.7.5"}
