In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix mbss changed flags corruption on 32 bit systems
On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding.
Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.
