All XillyUSB devices must have a Bulk IN and Bulk OUT endpoint at address 1. This is verified in xillyusb_setup_base_eps(). On top of that, a XillyUSB device may have additional Bulk OUT endpoints. The information about these endpoints' addresses is deduced from a data structure (the IDT) that the driver fetches from the device while probing it. These endpoints are checked in setup_channels(). A XillyUSB device never has more than one IN endpoint, as all data towards the host is multiplexed in this single Bulk IN endpoint. This is why setup_channels() only checks OUT endpoints. The Linux kernel CVE team has assigned CVE-2024-45011 to this issue. Affected and fixed versions =========================== Issue introduced in 5.14 with commit a53d1202aef1 and fixed in 5.15.166 with commit 25ee8b290820 Issue introduced in 5.14 with commit a53d1202aef1 and fixed in 6.1.107 with commit 4267131278f5 Issue introduced in 5.14 with commit a53d1202aef1 and fixed in 6.6.48 with commit 5cff754692ad Issue introduced in 5.14 with commit a53d1202aef1 and fixed in 6.10.7 with commit 1371d32b9597 Issue introduced in 5.14 with commit a53d1202aef1 and fixed in 6.11-rc4 with commit 2374bf7558de 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-2024-45011 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/char/xillybus/xillyusb.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/25ee8b2908200fc862c0434e5ad483817d50ceda https://git.kernel.org/stable/c/4267131278f5cc98f8db31d035d64bdbbfe18658 https://git.kernel.org/stable/c/5cff754692ad45d5086b75fef8cc3a99c30a1005 https://git.kernel.org/stable/c/1371d32b95972d39c1e6e4bae8b6d0df1b573731 https://git.kernel.org/stable/c/2374bf7558de915edc6ec8cb10ec3291dfab9594
