From: Greg Kroah-Hartman <[email protected]> Description =========== In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-esdhc-imx: use pm_runtime_resume_and_get() in suspend Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() to simplify error handling. pm_runtime_resume_and_get() automatically drops the usage counter on failure, avoiding the need for a separate pm_runtime_put_noidle() call. If it fails, the device is unclocked and accessing hardware registers would cause a kernel panic, so return the error immediately. The Linux kernel CVE team has assigned CVE-2026-68463 to this issue. Affected and fixed versions =========================== Issue introduced in 6.16 with commit 676a83855614635af3bf31ad3f8fec4031f81354 and fixed in 6.18.40 with commit 5b8f11cbe8ad5726b2b63ff1574d5cffa4df18c2 Issue introduced in 6.16 with commit 676a83855614635af3bf31ad3f8fec4031f81354 and fixed in 7.1.5 with commit 6355749aebf6c78081f7096a52edcd28d2aa0fab Issue introduced in 6.16 with commit 676a83855614635af3bf31ad3f8fec4031f81354 and fixed in 7.2-rc4 with commit 8da5930144712412d85e7f868693d96ec5c2018c 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-2026-68463 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-esdhc-imx.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/5b8f11cbe8ad5726b2b63ff1574d5cffa4df18c2 https://git.kernel.org/stable/c/6355749aebf6c78081f7096a52edcd28d2aa0fab https://git.kernel.org/stable/c/8da5930144712412d85e7f868693d96ec5c2018c
