In these cases, function handle_tx_event() should not proceed, because if 'ep->skip' is set, the pointer to the endpoint ring is used. To prevent a potential failure and make the code logical, return after checking the completion code for a Transfer event without TRBs. The Linux kernel CVE team has assigned CVE-2024-42226 to this issue. Affected and fixed versions =========================== Fixed in 6.1.98 with commit 948554f1bb16 Fixed in 6.1.99 with commit 1f4a10cb826f Fixed in 6.6.39 with commit 9a24eb8010c2 Fixed in 6.6.40 with commit 69bed24c8213 Fixed in 6.9.9 with commit c0ee01e8ba19 Fixed in 6.10 with commit 66cb618bf0bb 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-2024-42226 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/usb/host/xhci-ring.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/948554f1bb16e15b90006c109c3a558c66d4c4ac https://git.kernel.org/stable/c/1f4a10cb826fdec5cd442df010bcb3043bfd6464 https://git.kernel.org/stable/c/9a24eb8010c2dc6a2eba56e3eb9fc07d14ffe00a https://git.kernel.org/stable/c/69bed24c82139bbad0a78a075e1834a2ea7bd064 https://git.kernel.org/stable/c/c0ee01e8ba19ff7edc98f68a114d4789faa219b9 https://git.kernel.org/stable/c/66cb618bf0bb82859875b00eeffaf223557cb416
