In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Clamp MSI-X derived queue counts to avoid truncation ha-msixcount is u16, but ha-maxreqqueues, ha-maxrspqueues and ha-maxqpairs are u8. Deriving the queue count as "ha-maxreqqueues = ha-msixcount - 1" therefore...

CVE-2026-89856

A vulnerability in the Linux kernel qla2xxx SCSI driver arises from a type-width mismatch: ha->msix_count is u16 while derived queue counts (max_req_queues, max_rsp_queues, max_qpairs) are u8 . A device (physical or hot-plugged) advertising 257 MSI-X vectors causes msix_count - 1 to equal 256,...

CVE-2026-89790

CVE-2026-89790 is a divide-by-zero vulnerability in the Linux kernel IPv6 routing code, specifically in rt6_multipath_rebalance() (net/ipv6/route.c). Because RTM_NEWROUTE operates without the RTNL lock, a concurrent update to ignore_routes_with_linkdown can cause the first pass to compute a zero ...
