CVE-2026-80748

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the loongson2 MMC driver where the for each sg() macro is used incorrectly within the ls2k0500 mmc reorder cmd data() and ls2k2000 mmc reorder cmd data() functions. While the macro already iterates over scatterlist entries, the code incorrectly treats the sg pointer as an array base by using &sg[i] and sg dma len(&sg[i]). This results in the access of incorrect scatterlist entries or potential out-of-bounds memory access if the list is not structured as an array.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
