AZL-97350 CVE-2026-74597 affecting package kernel for versions less than 6.6.152.1-1

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip6ip6err ip6ip6err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6send. The clone still carries the outer packet's inet6skbparm in...

CVE-2026-74707

In the Linux kernel, the following vulnerability has been resolved: xsk: validate metadata when processing requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it again later when preparing the hardware request. User space can change the metadata...

CVE-2026-74708

In the Linux kernel, the following vulnerability has been resolved: xsk: validate launch-time metadata size Launch-time metadata extends beyond the first 16 bytes of struct xsktxmetadata. Reject the request when the registered metadata area does not contain the complete field. Snapshot the...

CVE-2026-74710

In the Linux kernel, the following vulnerability has been resolved: xsk: require at least 16 bytes of TX metadata AFXDP accepts a TX metadata length as small as eight bytes, but every supported request needs the flags plus at least one eight-byte request field. Such short metadata also lets the...

CVE-2026-74710

CVE-2026-74710 is an out-of-bounds read in the Linux kernel's AF_XDP (xsk) component. The mechanism accepts a TX metadata length as small as eight bytes, but every supported request requires the flags field plus at least one eight-byte request field (16 bytes minimum). When metadata shorter than ...

CVE-2026-74709

CVE-2026-74709 affects the AF_XDP (xsk) subsystem in the Linux kernel. The root cause is that user space can modify metadata flags after a TX request has been processed; when the kernel rereads those flags during completion, it may write a timestamp into the metadata area that was never requested...
