Dirty Frag Linux Kernel Local Privilege Escalation Vulnerability

The Dirty Frag vulnerability (CVE-2026-43284 and CVE-2026-43500) is a Linux kernel local privilege escalation that allows an unprivileged local user to gain root privileges by exploiting flaws in the networking subsystem to overwrite protected file contents in the page cache.

Local Privilege Escalation Vulnerability 'Copy Fail' in Linux Kernel

A local privilege escalation vulnerability, dubbed 'Copy Fail' (CVE-2026-31431), affects Linux kernels released since 2017, allowing an unprivileged local attacker to gain root permissions by exploiting a logic bug in the authencesn cryptographic template.

Linux Kernel proc_readdir_de() Use-After-Free Local Privilege Escalation

A local privilege escalation vulnerability exists in the Linux Kernel versions ~3.14+ through 6.18-rc5 due to a use-after-free in the proc_readdir_de() function, where a concurrent traversal can dereference a freed entry's fields during network device unregistration, leading to privilege escalation via modprobe_path overwrite.
