CVE-2026-53108 powerpc/64s: Fix unmap race with PMD migration entries

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fix unmap race with PMD migration entries The following race is possible with migration swap entries or device-private THP entries. e.g. when movepages is called on a PMD THP page, then there maybe an intermediate...

CVE-2026-53054

CVE-2026-53054 affects the Linux kernel DRM subsystem for Qualcomm Adreno (MSM) where an incorrect argument in VM_BIND UNMAP locking caused certain objects involved in UNMAP operations to not be consistently locked. The issue could impact system stability, particularly for non-NO_SHARE buffer obj...

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...
