If the timer callback (command_timer_fn) is already\nrunning when lbtf_free_cmd_buffer() frees the command array, the\ncallback dereferences priv->cur_cmd->cmdbuf which points to freed\nmemory.\n\nSwap the order so that timer_delete_sync() runs first, ensuring any\nin-flight callback has completed before the command buffers are freed.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/04c837d413dc11a91e0275b08b9e35a6c111175e","tags":[]},{"url":"https://git.kernel.org/stable/c/2b99bfc5a127ce8cd6a887d82815fc2e712f365b","tags":[]},{"url":"https://git.kernel.org/stable/c/3fb3663260ec396f86b733aab9f81fac6669d2fa","tags":[]},{"url":"https://git.kernel.org/stable/c/41b1a4d545ec348b7d5324b6d4f4c6a3e0326d46","tags":[]},{"url":"https://git.kernel.org/stable/c/b4745d6063758c681d33affca9733bbd356b6ea1","tags":[]},{"url":"https://git.kernel.org/stable/c/bbb9a0ab96d44a64529aafc7a16de460a1712f6a","tags":[]},{"url":"https://git.kernel.org/stable/c/e82536aad653e27c8ca7a8e0f6f816bc3f853ec3","tags":[]},{"url":"https://git.kernel.org/stable/c/f6c3fa0d17ca0c9e6033bb45f52e33b27a9a40e6","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
