CVE-2026-68750

CVE-2026-68750 affects the html_sanitize_ex crate (versions 0.3.1 up to, but not including, 1.5.3). The vulnerability is a quadratic-time CPU/memory exhaustion in the HTML traversal engine when sanitizing large sibling lists; the traverser recurses on the tail and repeatedly flattens lists, causi...

CVE-2026-68750 Quadratic sibling re-flattening in the html_sanitize_ex traversal engine allows CPU-exhaustion denial of service

Inefficient Algorithmic Complexity vulnerability in the traversal engine in rrrene htmlsanitizeex allows an unauthenticated remote attacker to exhaust server CPU and memory via a flat run of sibling elements in sanitized HTML. The list clause of HtmlSanitizeEx.Traverser.traverse/2 recurses on the...

kernel: A heap out-of-bounds write when function perf_read_group is called and sibling_list is smaller than its child's sibling_list

A flaw was found in the Linux kernel's Performance Events system component. A condition can be triggered that allows data to be written past the end or before the beginning of the intended memory buffer. This issue may lead to a system crash, code execution, or local privilege escalation...

SUSE CVE-2023-5717

A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events perf component can be exploited to achieve local privilege escalation. If perfreadgroup is called while an event's siblinglist is smaller than its child's siblinglist, it can increment or write to memor...
