This is not the case, as the interrupt handler can already be running, which would lead to the ISP being disabled while the interrupt handler handling a captured frame. This brings up two issues: 1) the ISP could be powered off while the interrupt handler is still running and accessing registers, leading to board lockup, and 2) the interrupt handler code and the code that disables the streaming might do things that conflict. It is not clear to me if 2) causes a real issue, but 1) can be seen with a suitable delay (or printk in my case) in the interrupt handler, leading to board lockup. The Linux kernel CVE team has assigned CVE-2023-52589 to this issue. Affected and fixed versions =========================== Fixed in 6.1.77 with commit bf808f58681c Fixed in 6.6.16 with commit fab483438342 Fixed in 6.7.4 with commit 7bb1a2822aa2 Fixed in 6.8-rc1 with commit 870565f063a5 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-2023-52589 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/media/platform/rockchip/rkisp1/rkisp1-csi.c drivers/media/platform/rockchip/rkisp1/rkisp1-isp.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/bf808f58681cab64c81cd814551814fd34e540fe https://git.kernel.org/stable/c/fab483438342984f2a315fe13c882a80f0f7e545 https://git.kernel.org/stable/c/7bb1a2822aa2c2de4e09bf7c56dd93bd532f1fa7 https://git.kernel.org/stable/c/870565f063a58576e8a4529f122cac4325c6b395
