CVE-2026-98584

The Linux kernel contains a potential stack information leak within the net/sched component. The em_text_dump() function allocates struct tcf_em_text on the stack without zeroing it. Because strscpy() was used instead of strncpy(), the remaining bytes of the structure remain uninitialized. These ...

CVE-2026-98442

The Linux kernel contains a Use-After-Free (UAF) vulnerability within the net/sched: act_ct component. The issue occurs because a raw pointer to the extensions area is inserted into the expectations list during the nf_ct_helper() call sequence. If a connection is not yet confirmed, subsequent *_e...

CVE-2026-98441 net/sched: act_ct: avoid modifying shared unconfirmed ct entry

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: avoid modifying shared unconfirmed ct entry In a case where skb with an unconfirmed ct entry gets cloned, we may end up processing both again but with different sets of extensions. The series of events: 1. The...

CVE-2026-98441

The Linux kernel contains a vulnerability in the net/sched: act_ct component where cloning an skb with an unconfirmed conntrack (ct) entry can lead to a Use-After-Free (UAF) . This occurs because the first clone may wire up an extension pointer into the expectation list, but if it loses confirmat...
