Improper Validation of Array Index Affecting python3-perf package, versions *
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

wifi: ath11k: Fix SKB corruption in REO destination ring
While running traffics for a long time, randomly an RX descriptor filled with value "0" from REO destination ring is received. This descriptor which is invalid causes the wrong SKB (SKB stored in the IDR lookup with buffer id "0") to be fetched which in turn causes SKB memory corruption issue and the same leads to crash after some time.
Changed the start id for idr allocation to "1" and the buffer id "0" is reserved for error validation. Introduced Sanity check to validate the descriptor, before processing the SKB.
Crash Signature :
