CVE-2026-80931

CVE-2026-80931 is an out-of-bounds read in the Linux kernel's DS28E17 1-Wire to I2C bridge driver (w1: ds28e17). During an I2C_M_RECV_LEN read, the device-controlled length byte (buf[0]) is not validated against the caller buffer size (34 bytes), allowing a read up to ~222 bytes out of bounds . P...

CVE-2026-80931 w1: ds28e17: reject an oversize length on an I2C block read

In the Linux kernel, the following vulnerability has been resolved: w1: ds28e17: reject an oversize length on an I2C block read w1f19i2cmastertransfer is the masterxfer for the DS28E17 1-Wire to I2C bridge. On an I2CMRECVLEN read, it takes the length from the device. The downstream slave puts a...

CVE-2026-80930

CVE-2026-80930 affects the Linux kernel 's tpm_i2c_nuvoton driver (Nuvoton TPM over I2C). The root cause is in i2c_nuvoton_wait_for_stat(), which enables the IRQ before waiting for the interrupt handler to report a status change. If the wait times out or is interrupted before the handler runs, th...

CVE-2026-80928

CVE-2026-80928 is a Use-After-Free (UAF) of struct cred in the Linux kernel's SMACK (Simplified Mandatory Access Control Kernel) security module, specifically in smack_file_send_sigiotask(). The root cause is that the function accessed the subjective credential pointer (tsk->cred) on a non-cur...

CVE-2026-80929

CVE-2026-80929 affects the Linux kernel's sysctl subsystem . The cad_pid entry, which controls the PID killed on control-alt-delete and is logically global to the root namespace, was placed in pid_table[] with permissions governed by pid_table_root_permissions(). This allowed a non-root local use...
