CVE-2026-89844

CVE-2026-89844 is a locking race in the Linux kernel qla2xxx SCSI driver. In qla24xx_report_id_acquisition(), the format-1 path drops vport_slock after taking the vport reference and then calls qla_update_host_map() without holding the lock. That function mutates the ha->host_map btree via btr...

CVE-2026-89843

CVE-2026-89843 affects the Linux kernel scsi: qla2xxx driver (QLogic). Several bsg handlers use an uninitialized 256-byte on-stack buffer (uint8_t bsg[DMA_POOL_SIZE]) that is filled via sg_copy_to_buffer(), which copies only the user-supplied request length. When the request is shorter than the s...

CVE-2026-89841

CVE-2026-89841 affects the f2fs filesystem in the Linux kernel . The flaw resides in redirty_blocks(), where a do/while loop introduced by commit 5951fee46bef causes an extra iteration when read_cache_folio() fails before any folio is pinned. If readahead has already populated the failed folio in...
