DEBIAN-CVE-2026-55213
h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit edd7a120bfc4af11ac0cbebce2a43cc1f93f9af1, when h2o processes a QPACK instruction sent from the peer over HTTP/3, lib/http3/qpack.c might allocate an on-stack buffer as large as approximately 800 KB by calling...
kernel: x86: local privesc due to bad_iret and paranoid entry incompatibility
A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a SS stack segment fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system...

USN-2446-1 linux vulnerabilities
Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment SS register in the x86 architecture. A local attacker could exploit this flaw to gain administrative privileges. CVE-2014-9322 An information leak in the Linux kernel was discovered...
Debian DSA-921-1 : kernel-source-2.4.27 - several vulnerabilities
Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2005-0756 Alexander Nyberg discovered that the ptra...
Ubuntu 4.10 / 5.04 : linux-source-2.6.10, linux-source-2.6.8.1 vulnerabilities (USN-187-1)
A Denial of Service vulnerability was detected in the stack segment fault handler. A local attacker could exploit this by causing stack fault exceptions under special circumstances scheduling, which lead to a kernel crash. CAN-2005-1767 Vasiliy Averin discovered a Denial of Service vulnerability ...
CVE-2005-1767
CVE-2005-1767 affects Linux kernels 2.4.x and 2.6.x; the vulnerability exists in traps.c stack fault handler, allowing a local user to cause a kernel crash (Denial of Service) via stack exceptions. Public advisories (Debian, Red Hat/CentOS, Ubuntu) indicate updated kernel packages mitigate the is...
