CVE-2026-19248

A flaw was found in Qt. This vulnerability, specifically an unbounded recursion in the QDomNode destructor during QDomDocument XML parsing, allows a remote attacker to trigger a denial-of-service DoS crash. By processing untrusted XML input, the affected system can become unresponsive, leading to...

CVE-2026-80841 net/packet: defer vmalloc TX_RING free until skbs finish

In the Linux kernel, the following vulnerability has been resolved: net/packet: defer vmalloc TXRING free until skbs finish AFPACKET TXRING skbs keep a raw pointer to their ring frame. The skb page references preserve page-backed ring blocks after pgvec is freed, but they do not preserve a vmallo...

CVE-2026-80841

CVE-2026-80841 is a use-after-free in the Linux kernel's AF_PACKET TX_RING subsystem. AF_PACKET TX_RING skbs hold a raw pointer to their ring frame; while page references preserve page-backed ring blocks after the ring vector is freed, they do not preserve a vmalloc mapping. This means a late skb...
