Executing the argument function synchronously from within dpm_async_fn() may also be problematic for ordering reasons (it may cause a consumer device's resume callback to be invoked before a requisite supplier device's one, for example). Address this by changing the code in question to use async_schedule_dev_nocall() for scheduling the asynchronous execution of device suspend and resume functions and to directly run them synchronously if async_schedule_dev_nocall() returns false. The Linux kernel CVE team has assigned CVE-2023-52498 to this issue. Affected and fixed versions =========================== Fixed in 5.10.210 with commit f46eb832389f Fixed in 5.15.149 with commit a1d62c775b07 Fixed in 6.1.76 with commit e1c9d32c9830 Fixed in 6.6.15 with commit e681e29d1f59 Fixed in 6.7.3 with commit 9bd3dce27b01 Fixed in 6.8-rc1 with commit 7839d0078e0d Please see https://www.kernel.org or 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-2023-52498 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/base/power/main.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/f46eb832389f162ad13cb780d0b8cde93641990d https://git.kernel.org/stable/c/a1d62c775b07213c73f81ae842424c74dd14b5f0 https://git.kernel.org/stable/c/e1c9d32c98309ae764893a481552d3f99d46cb34 https://git.kernel.org/stable/c/e681e29d1f59a04ef773296e4bebb17b1b79f8fe https://git.kernel.org/stable/c/9bd3dce27b01c51295b60e1433e1dadfb16649f7 https://git.kernel.org/stable/c/7839d0078e0d5e6cc2fa0b0dfbee71de74f1e557
