From bippy-a5840b7849dd Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman To: Reply-to: , Subject: CVE-2024-36029: mmc: sdhci-msm: pervent access to suspended controller Description =========== In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-msm: pervent access to suspended controller Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly. The Linux kernel CVE team has assigned CVE-2024-36029 to this issue. Affected and fixed versions =========================== Issue introduced in 4.10 with commit 67e6db113c90 and fixed in 5.15.158 with commit 1200481cd606 Issue introduced in 4.10 with commit 67e6db113c90 and fixed in 6.1.90 with commit a957ea5aa3d3 Issue introduced in 4.10 with commit 67e6db113c90 and fixed in 6.6.30 with commit 56b99a52229d Issue introduced in 4.10 with commit 67e6db113c90 and fixed in 6.8.9 with commit f653b04a818c Issue introduced in 4.10 with commit 67e6db113c90 and fixed in 6.9 with commit f8def10f73a5 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-2024-36029 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/mmc/host/sdhci-msm.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/1200481cd6069d16ce20133bcd86f5825e26a045 https://git.kernel.org/stable/c/a957ea5aa3d3518067a1ba32c6127322ad348d20 https://git.kernel.org/stable/c/56b99a52229d7f8cd1f53d899f57aa7eb4b199af https://git.kernel.org/stable/c/f653b04a818c490b045c97834d559911479aa1c5 https://git.kernel.org/stable/c/f8def10f73a516b771051a2f70f2f0446902cb4f
