Loading vulnerability…
A shift-out-of-bounds vulnerability was present in the Linux kernel's nvmem subsystem, specifically in the logic handling cells with 'nbits' equal to a multiple of BITS_PER_BYTE. The code attempted to generate a mask using GENMASK with a negative shift value, resulting in undefined behavior when the shift exponent exceeded the width of the type. This could be triggered during nvmem cell reads, as reported by UBSAN in drivers/nvmem/core.c.

Linux kernel NVMEM shift-out-of-bounds flaw.
Linux kernel NVMEM flaw involving an out-of-bounds shift with byte-sized cells.
A Linux kernel NVMEM subsystem shift-out-of-bounds issue affecting byte-size cells, detected through UBSAN. The referenced automated assessment characterizes its approximate impact as low.
A Linux kernel NVMEM subsystem vulnerability in which byte-sized cells with an nbits value divisible by BITS_PER_BYTE can trigger an undefined out-of-bounds shift. Red Hat rates it Low (CVSS 4.4), while NVD rates it 7.8. The issue may cause a crash and potentially permit out-of-bounds memory disclosure depending on context.
