Because we did not check the return value, we also did not free the skb in the error path. The Linux kernel CVE team has assigned CVE-2026-64155 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath11k/wmi.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/d6c7b8d0dc22c0a8743435db8f42d98524b70df3 https://git.kernel.org/stable/c/cd43d587dd333517c806cd24696e6e1a26b9951e https://git.kernel.org/stable/c/3d675896ea03aca631852a2a7e91e6cb8f664967 https://git.kernel.org/stable/c/008955b1348452de25bc19d6e0f0f673d4cb9a3c https://git.kernel.org/stable/c/acde4692afcdaea6de3e2996ddfaeaa7ae6b0130 https://git.kernel.org/stable/c/d618d322b95c80d5ad7091f35a7193e4050dcc27 https://git.kernel.org/stable/c/55dda532bbc261aef495e403c8900c5e2ab5fa34
