New API: Redis user quota cache overwrite via PUT /api/user/self allows quota bypass

Summary Authenticated users can repeatedly call PUT /api/user/self with language or sidebarmodules while relay requests are consuming quota. The settings path reads a full User snapshot and writes it back through User.Update, which refreshes Redis with RedisHSetObj and overwrites the Quota field...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
