Add a goto skip instead of return, to ensure event and all the list entries are freed properly. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 The Linux kernel CVE team has assigned CVE-2023-53767 to this issue. Affected and fixed versions =========================== Fixed in 6.3.4 with commit a87f59041a7f77b4bdab05cea60ac6adc69dc5d2 Fixed in 6.4 with commit 960412bee0ea75f6b3c2dca4a3535795ee84c47a Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2023-53767 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath12k/qmi.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/a87f59041a7f77b4bdab05cea60ac6adc69dc5d2 https://git.kernel.org/stable/c/960412bee0ea75f6b3c2dca4a3535795ee84c47a
