CVE-2026-53021

CVE-2026-53021 affects the Linux kernel SCSI target core (UNMAP bounds check). The root cause is an overflow where LBA + range can wrap on 64-bit overflow, with a fix that adds an overflow check mirroring the pattern used for WRITE_SAME. Publicly noted patches exist across multiple OS families: R...

CVE-2026-53009

The CVE-2026-53009 issue affects the Linux kernel ice network driver. When ice_tso() or ice_tx_csum() fail, the error path in ice_xmit_frame_ring() frees the skb, but the first tx_buf may still reference it and be marked ICE_TX_BUF_SKB, with next_to_use unchanged. If there is no subsequent packet...
