Take st_nci_i2c_remove as an example. In st_nci_i2c_probe, it called ndlc_probe and bound &ndlc->sm_work with llt_ndlc_sm_work. When it calls ndlc_recv or timeout handler, it will finally call schedule_work to start the work. When we call st_nci_i2c_remove to remove the driver, there may be a sequence as follows: Fix it by finishing the work before cleanup in ndlc_remove CPU0 CPU1 |llt_ndlc_sm_work st_nci_i2c_remove | ndlc_remove | st_nci_remove | nci_free_device| kfree(ndev) | //free ndlc->ndev | |llt_ndlc_rcv_queue |nci_recv_frame |//use ndlc->ndev The Linux kernel CVE team has assigned CVE-2023-53106 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/nfc/st-nci/ndlc.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/2156490c4b7cacda9a18ec99929940b8376dc0e3 https://git.kernel.org/stable/c/3405eb641dafcc8b28d174784b203c1622c121bf https://git.kernel.org/stable/c/b0c202a8dc63008205a5d546559736507a9aae66 https://git.kernel.org/stable/c/43aa468df246175207a7d5d7d6d31b231f15b49c https://git.kernel.org/stable/c/84dd9cc34014e3a3dcce0eb6d54b8a067e97676b https://git.kernel.org/stable/c/5e331022b448fbc5e76f24349cd0246844dcad25 https://git.kernel.org/stable/c/f589e5b56c562d99ea74e05b1c3f0eab78aa17a3 https://git.kernel.org/stable/c/5000fe6c27827a61d8250a7e4a1d26c3298ef4f6
