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: bpf: Fix oob access in cgroup local
storage Lonial reported that an out-of-bounds access in cgroup local storage can be crafted via tail
calls. Given two programs each utilizing a cgroup local storage with a different value size, and one
program doing a tail call into the other. The verifier will validate each of the indivial programs just
fine. However, in the runtime context the bpf_cg_run_ctx holds an bpf_prog_array_item which contains the
BPF program as well as any cgroup local storage flavor the program uses. Helpers such as
bpf_get_local_storage() pick this up from the runtime context: ctx = container_of(current->bpf_ctx, struct
bpf_cg_run_ctx, run_ctx); storage = ctx->prog_item->cgroup_storage[stype]; if (stype ==
BPF_CGROUP_STORAGE_SHARED) ptr = &READ_ONCE(storage->buf)->data[0]; else ptr =
this_cpu_ptr(storage->percpu_buf); For the second program which was called from the originally attached
one, this means bpf_get_local_storage() will pick up the former program's map, not its own. With
mismatching sizes, this can result in an unintended out-of-bounds access. To fix this issue, we need to
extend bpf_map_owner with an array of storage_cookie[] to match on i) the exact maps from the original
program if the second program was using bpf_get_local_storage(), or ii) allow the tail call combination if
the second program was not using any of the cgroup local storage maps. (CVE-2025-38502)
