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...

CVE-2026-63959

The CVE-2026-63959 vulnerability affects the Linux kernel USB Type-C support (tcpm/tcpci_maxim). A broken/malicious USB-C port could transmit a CRC-valid frame where the header advertises up to seven data objects but the body carries fewer, causing the driver to read from uninitialized stack memo...

CVE-2026-63957

The CVE-2026-63957 issue affects the Linux kernel USB serial safe_serial implementation. The vulnerability is a memory corruption risk when using a small endpoint, arising from an inadequately sized bulk-out buffer; in safe mode, a malicious device reporting a smaller size could lead to user-cont...
