CVE-2026-26201 emp3r0r Affected by Concurrent Map Access DoS (panic/crash)

emp3r0r is a C2 designed by Linux users for Linux environments. Prior to version 3.21.2, multiple shared maps are accessed without consistent synchronization across goroutines. Under concurrent activity, Go runtime can trigger fatal error: concurrent map read and map write, causing C2 process cra...

kernel: Linux kernel: Use-after-free in proc_readdir_de() can lead to privilege escalation or denial of service.

A flaw was found in the Linux kernel. This use-after-free UAF vulnerability occurs in the procreaddirde function within the /proc filesystem. A local attacker with low privileges can exploit this by concurrently traversing specific directories while network devices are unregistered. This can lead...
