The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - bpf: Fix undefined behavior in interpreter sdiv/smod for INT_MIN The BPF interpreter's signed 32-bit     division and modulo handlers use the kernel abs() macro on s32 operands. The abs() macro documentation     (include/linux/math.h) explicitly states the result is undefined when the input is the type minimum. When     DST contains S32_MIN (0x80000000), abs((s32)DST) triggers undefined behavior and returns S32_MIN unchanged     on arm64/x86. This value is then sign-extended to u64 as 0xFFFFFFFF80000000, causing do_div() to compute     the wrong result. The verifier's abstract interpretation (scalar32_min_max_sdiv) computes the     mathematically correct result for range tracking, creating a verifier/interpreter mismatch that can be     exploited for out-of-bounds map value access. Introduce abs_s32() which handles S32_MIN correctly by     casting to u32 before negating, avoiding signed overflow entirely. Replace all 8 abs((s32)...) call sites     in the interpreter's sdiv32/smod32 handlers. s32 is the only affected case -- the s64 division/modulo     handlers do not use abs(). (CVE-2026-31525)

Note that Nessus relies on the presence of the package as reported by the vendor.
