CVE-2026-74726

A race condition in the Linux kernel's bonding module affects the Active-Backup Load Balancing (ALB) monitor (bond_alb_monitor() in drivers/net/bonding/bond_alb.c). The function reads primary_is_promisc under RCU, then drops RCU and acquires RTNL via rtnl_trylock(). In that window, the active sla...

CVE-2026-74715

CVE-2026-74715 is a race condition in the Linux kernel BPF conntrack kfuncs (__bpf_nf_ct_lookup() and __bpf_nf_ct_alloc_entry()). The opts argument can reference a shared BPF map value, and opts->netns_id is read independently during namespace reference acquisition and release. A concurrent wr...

CVE-2026-74704 net/sched: sch_cake: drop WARN_ON(1) for malformed packets in ACK filter

In the Linux kernel, the following vulnerability has been resolved: net/sched: schcake: drop WARNON1 for malformed packets in ACK filter The schcake ACK filter parses packets to find the TCP header and filter duplicated ACKs if the flow is backlogged.

CVE-2026-74703

CVE-2026-74703 affects the Linux kernel's vhost-scsi component. When T10 Protection Information (PI) is negotiated, a malformed request can declare protection bytes that cover or exceed the full payload length. This causes a zero data SGL count to reach sg_alloc_table_chained() , triggering a BUG...
