CVE-2025-21653

CVE-2025-21653 affects the Linux kernel net_sched flow classifier (net/sched/cls_flow.c). The vulnerability was due to missing validation of TCA_FLOW_RSHIFT, which could trigger undefined behavior (UB) and a shift-out-of-bounds on large 32-bit shifts, as shown by UBSAN. Connected advisories (Astr...
