CVE-2026-64180

The CVE-2026-64180 entry documents a Linux kernel issue in the memory hotplug path (mm/memory_hotplug). The root cause is that remove_memory_blocks_and_altmaps() calls find_memory_block() to obtain a memory block device reference, but the acquired reference is not dropped, leading to a leaked dev...

CVE-2026-64135

In the Linux kernel hwmon driver for pmbus/adm1266, the function adm1266_nvmem_read_blackbox() allocated a 5-byte stack buffer and passed it to i2c_smbus_read_block_data(), which copies data.block[0] bytes from the SMBus block into the caller buffer. If the device returns a length greater than 5,...

CVE-2026-64086

The CVE-2026-64086 issue affects the Linux kernel PMBUS adm1266 hwmon path. A read transaction for the pmbus_block_xfer path set .len to ADM1266_PMBUS_BLOCK_MAX + 2 while read_buf was declared as ADM1266_PMBUS_BLOCK_MAX + 1. For max-length block responses, this allowed writing 257 bytes into a 25...
