CVE-2026-98012

The Linux kernel contains a vulnerability in the net/sched: sfq component where the sfq_change() function fails to properly restrict the quantum value. By providing a crafted size table causing qdisc_pkt_len to reach approximately 2 GiB, an attacker can set quantum=1 to trigger a deficit-refill l...

CVE-2026-97530

The Linux kernel contains a vulnerability in the scsi: qla2xxx driver where the functions qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() incorrectly poll for a specific signature (0xDEADDEAD ) to determine if the next continuation IOCB has arrived. Because a continuation IOCB carries raw...
