This ensures that skb_kfree_head() can reliably use skb_end_offset to distinguish skb heads allocated from skb_small_head_cache vs. generic kmalloc caches.  However, when KFENCE is enabled, kfence_ksize() returns the exact requested allocation size instead of the slab bucket size. If a caller (e.g. bpf_test_init) allocates skb head data via kzalloc() and the requested size happens to equal SKB_SMALL_HEAD_CACHE_SIZE, then slab_build_skb() -> ksize() returns that exact value. After subtracting skb_shared_info overhead, skb_end_offset ends up matching SKB_SMALL_HEAD_HEADROOM, causing skb_kfree_head() to incorrectly free the object to skb_small_head_cache instead of back to the original kmalloc cache, resulting in a slab cross-cache free:    kmem_cache_free(skbuff_small_head): Wrong slab cache. Expected   skbuff_small_head but got kmalloc-1k  Fix this by always calling kfree(head) in skb_kfree_head(). This keeps the free path generic and avoids allocator-specific misclassification for KFENCE objects.",null,[],[],[],[14],{"_key":15},"CVE-2026-31429",[],[],[],"2026-04-20T10:16:16.737Z","2026-06-15T19:06:15.460009145Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2026-31429",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},5.5,"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H",6,4.6,[40],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,50,51,55],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":52,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":53,"version_end_type":54,"fixed_in":9},"lt6_12_85_1","6.12.85-1","excluding",{"version":56,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":57,"version_end_type":54,"fixed_in":9},"lt6_19_13_1","6.19.13-1"]
