kernel: nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
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 BITSPERBYTE the logic p &= GENMASKcell-nbits%BITSPERBYTE - 1, 0; will become undefined behavior because nbits modulo BITSPERBYT...
kernel: bounds: Use the right number of bits for power-of-two CONFIG_NR_CPUS
A vulnerability was found in the Linux kernel related to the improper handling of power-of-two values for CONFIGNRCPUS. The bitsper function incorrectly rounds up to the next power of two when given a power of two, causing crashes on certain systems...
