Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net: add pskb_may_pull() to
 skb_gro_receive_list() skb_gro_receive_list() calls skb_pull(skb, skb_gro_offset(skb)) without first
 ensuring the data is in the linear area via pskb_may_pull(). When the skb arrives via napi_gro_frags(),
 skb_headlen can be 0 (all data in page fragments) while skb_gro_offset is non-zero (after IP+TCP header
 parsing). The skb_pull() then decrements skb->len by skb_gro_offset but skb->data_len stays unchanged,
 hitting BUG_ON(skb->len < skb->data_len) in __skb_pull(). The UDP fraglist GRO path already contains this
 guard at udp_offload.c:749. Adding it to skb_gro_receive_list() itself provides centralized protection for
 all callers (TCP, UDP, and any future protocols), and ensures the precondition of skb_pull() is satisfied
 before it is called. On pskb_may_pull() failure, set NAPI_GRO_CB(skb)->flush = 1 so the skb is not held as
 a new GRO head and is instead delivered through the normal receive path, matching the UDP handling.
 (CVE-2026-53235)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19907.0.0 or later.
