CVE-2026-98755

A vulnerability exists in the Linux kernel within the tty: vcc component. The vcc_send_ctl() function fails to fully zero-initialize the stack-allocated struct vio_vcc pkt structure. Specifically, the tag.stype_env field remains uninitialized before being transmitted via ldc_write(), which can re...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.12.113, 6.18.56, and 7.2.10 contain security vulnerabilities. These vulnerabilities stem from the viovcc structure used in vccsendctl, where the packet associated with the stack allocation is not fully initialized. As a result, the tag.stypeenv field is not...
