snapd snap-confine / systemd-tmpfiles Race Condition LPE (CVE-2026-3888)
snap-confine's writable-mimic setup performs a directory swap while constructing a snap's mount namespace, and races with systemd-tmpfiles during this window. A local attacker can exploit this race to poison the namespace being constructed for a privileged…
PackageKit TOCTOU Local Privilege Escalation (CVE-2026-41651)
PackageKit's transaction handling in src/pk-transaction.c contains a set of logic flaws that combine into a TOCTOU (time-of-check to time-of-use) race condition, nicknamed "Pack2TheRoot" by the researcher. InstallFiles() overwrites cached transaction…
npm `tar` Package Unicode-Normalization Race Condition / File Collision (CVE-2026-2395)
The tar npm package's parallel-extraction mode (jobs > 1) is vulnerable to a race condition rooted in Unicode normalization differences: filenames like collisionss and collisionß can be treated as the same target path due to case/normalization handling, even…
FreeBSD exec_args_adjust_args() Out-of-Bounds memmove — Local Privilege Escalation via sshd Race (CVE-2026-7270)
An operator-precedence bug in FreeBSD's execargsadjustargs() (present since 2013) computes a memmove size using + consume instead of - consume, causing the copy length to be roughly double the correct value. With a ~265KB argv[0] supplied via a shebang exec,…
Discuz! X5.0 Race Condition + CAPTCHA-Solving Pre-Auth to RCE Chain (CVE-2026-49952)
