CVE-2026-52995

Summary (concrete details from connected docs): CVE-2026-52995 affects the Linux kernel RDS info paths (RDS/IB and RDS6/IB visitors). The root cause is that rds_for_each_conn_info() and rds_walk_conn_path_info() pass a caller-allocated on‑stack u64 buffer to visitors and then copy full item_len b...

In the Linux kernel, the following vulnerability has been resolved: net/rds: zero per-item info buffer before handing it to visitors rdsforeachconninfo and rdswalkconnpathinfo both hand a caller-allocated on-stack u64 buffer to a per-connection visitor and then copy the full itemlen bytes back to...

CVE-2026-52985

CVE-2026-52985 concerns the Linux kernel in the netdevsim feature, where the IP header in a dummy skb was not zero-initialized in nsim_dev_trap_skb_build. The issue arises from using skb_put instead of skb_put_zero, leading to uninitialized values in the IP header and potential memory/safety impl...

CVE-2026-52968

CVE-2026-52968 affects the Linux kernel KVM on s390. The root cause is double-scaling the GAIT table index: code in kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and aen_host_forward() multiplies the GAIT index by sizeof(struct zpci_gaite) even though gait is already a pointer to struct ...
