CVE-2026-48984 pam_usb: xfree() does not call explicit_bzero — sensitive cryptographic material may linger in freed heap

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, the xfree memory release helper in calls free without first zeroing the buffer contents, releasing heap-allocated buffers containing sensitive data — including one-time pad bytes read fr...

CVE-2026-45874

A flaw was found in the Linux kernel, within the phy: freescale: imx8qm-hsio component. This vulnerability occurs when a specific pointer, refclkpad, is not properly initialized and is later used without validation. This can lead to a NULL pointer dereference, which may cause the system to crash...
