Loading vulnerability…
CVE-2024-35888 is a Linux kernel ERSPAN packet-processing vulnerability affecting the ip6erspan_rcv() and erspan_rcv() receive paths. The functions could read the erspan_base_hdr version field without first ensuring that the header was present in the linear skb->head region. Processing a non-linear socket buffer can therefore result in use of uninitialized memory. The fix adds pskb_may_pull() checks before accessing the ERSPAN base header and reloads the IP-header pointer in erspan_rcv() after pulling data because skb->head may change.

A Linux kernel ERSPAN packet-processing flaw affecting the ip6erspan_rcv() and erspan_rcv() paths. Improper validation of packet-buffer header availability can result in use of uninitialized data and an availability impact; the cited CVSS v3 vector rates it 5.5 (local, low complexity, low privileges, no user interaction, high availability impact).
A locally exploitable, low-complexity vulnerability requiring low privileges that can cause high availability impact; the supplied content does not identify the affected component or flaw mechanism.
An insufficient packet-header presence check in Linux kernel ERSPAN processing.
A Linux kernel ERSPAN vulnerability involving validation that the ERSPAN base header is present in the packet buffer head.
