CVE-2026-89440

CVE-2026-89440 affects the Linux kernel's via-sdmmc MMC driver . The root cause is a use-after-free that occurs when mmc_add_host() fails during device probe: the SD card-detect interrupt (request_irq()) remains registered and its handler (via_sdc_isr()) continues to dereference the freed host st...

PT-2026-90156

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the via-sdmmc driver where the SD card-detect interrupt remains registered if mmc add host fails during the probe process. Because the error path only unmaps registers...
