22 May 2024 — In the Linux kernel, the following vulnerability has been resolved: nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0); will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long. In the Linux kernel, the following vulnerabil... • https://git.kernel.org/stable/c/69aba7948cbe53f2f1827e84e9dd0ae470a5072e • CWE-125: Out-of-bounds Read •
