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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/04c837d413dc11a91e0275b08b9e35a6c111175e","https://git.kernel.org/stable/c/2b99bfc5a127ce8cd6a887d82815fc2e712f365b","https://git.kernel.org/stable/c/3fb3663260ec396f86b733aab9f81fac6669d2fa","https://git.kernel.org/stable/c/41b1a4d545ec348b7d5324b6d4f4c6a3e0326d46","https://git.kernel.org/stable/c/b4745d6063758c681d33affca9733bbd356b6ea1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98194","score":0.00177,"percentile":0.07148,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
