PatchTheCVECVE-2026-98952: In the Linux kernel, the following vulnerability has been resolved: pfcp: make sure the SEID is linear before
CVE-2026-98952 is a high-severity flaw (CVSS 7.3) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In the Linux kernel, the following vulnerability has been resolved: pfcp: make sure the SEID is linear before reading it pfcp_encap_recv() only makes sure that the UDP header and the 4 byte PFCP header are in the linear area. When the S flag is set, pfcp_session_recv() then reads the 8 byte SEID that follows, which is not covered by the pskb_may_pull() check. A short PFCP packet with the S flag set, or one whose session header lies in a fragme
