{"apiVersion":"1.0","identifier":"CVE-2026-72110","description":"In the Linux kernel, the following vulnerability has been resolved: bpf,fork: wipe ->bpf_storage before bailouts that access it Currently, copy_process() can bail out to free_task() before p->bpf_storage has been initialized, with this call graph (shown here for the !CONFIG_MEMCG case): copy_process dup_task_struct arch_dup_task_struct [copies the entire task_struct, including ->bpf_storage member] [RLIMIT_NPROC check fails] delayed_free_task free_task bpf_task_storage_free rcu_dereference(task->bpf_storage) bpf_local_storage_destroy In this case, the nascent task-s ->bpf_storage member that bpf_local_storage_destroy() operates on is a plain copy of the parent-s ->bpf_storage pointer, not a real initialized pointer. This leads to badness (kernel hangs, UAF). This is reachable as long as the process calling fork() has been inserted into a task storage map.","publishedAt":"2026-08-15T06:21:25","lastModifiedAt":"2026-08-23T13:16:40","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72110","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72110","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72110","en":"https://www.redsauce.net/en/cves/CVE-2026-72110","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72110","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72110","de":"https://www.redsauce.net/de/cves/CVE-2026-72110","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72110","el":"https://www.redsauce.net/el/cves/CVE-2026-72110"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72110"}}
