  "details": "In the Linux kernel, the following vulnerability has been resolved:  neighbour: Enforce min/max to NDTPA_INTERVAL_PROBE_TIME_MS.  NDTPA_INTERVAL_PROBE_TIME_MS sets .type and .min but misses .validation_type, so no validation is applied:    # ynl --family rt-neigh --do setneightbl \\   --json '{\"name\": \"arp_cache\", \"parms\": {\"interval-probe-time-ms\": 0}}'    # ynl --family rt-neigh --dump getneightbl --output-json | \\   jq '.[] | select(.name == \"arp_cache\" and has(\"config\"))           | .parms[\"interval-probe-time-ms\"]'   0  Moreover, nla_get_msecs() uses msecs_to_jiffies(), and u64 is silently cast to u32, so a larger value can bypass the min check:    e.g. 4294967296 == 0x100000000    # ynl --family rt-neigh --do setneightbl \\   --json '{\"name\": \"arp_cache\", \"parms\": {\"interval-probe-time-ms\": 4294967296}}'    # ynl --family rt-neigh --dump getneightbl --output-json | \\   jq '.[] | select(.name == \"arp_cache\" and has(\"config\"))           | .parms[\"interval-probe-time-ms\"]'   0  msecs_to_jiffies() returns MAX_JIFFY_OFFSET if the value is larger than INT_MAX.  Also, INT_MAX ms overflows int NEIGH_VAR() when HZ \u003e 1000 (Alpha, MIPS), and passing a negative integer to queue_delayed_work(unsigned long delay) causes sign extension, which wraps around the expiry time to the past, resulting in it being handled as 0 delay in the timer wheel.  Let's use NLA_POLICY_FULL_RANGE() and limit the max to 1 day.  The same max check is applied to sysctl as well.  Note that this controls the probe interval for NTF_MANAGED entries, so the max of 1 day is unlikely to break any deployments.",
