In the Linux kernel, the following vulnerability has been resolved: net: ioam6: fix OOB and missing lock When trace-type.bit6 is set: if trace-type.bit6 ... queue = skbgettxqueuedev, skb; qdisc = rcudereferencequeue-qdisc; This code can lead to an out-of-bounds access of the dev-tx array when...

CVE-2026-43101 ipv6: ioam: fix potential NULL dereferences in __ioam6_fill_trace_data()

In the Linux kernel, the following vulnerability has been resolved: ipv6: ioam: fix potential NULL dereferences in ioam6filltracedata We need to check in6devget for possible NULL value, as suggested by Yiming Qian. Also add skbdstdevrcu instead of skbdstdev, and two missing READONCE. Note that @d...

CVE-2026-43101

The CVE-2026-43101 entry refers to a Linux kernel IPv6 IOAM issue: __ioam6_fill_trace_data() could dereference NULL if __in6_dev_get() returns NULL. The fix replaces skb_dst_dev() with skb_dst_dev_rcu() and adds two missing READ_ONCE() checks; it also enforces that @dev cannot be NULL. Patches ar...

CVE-2026-43083

The CVE pertains to Linux kernel ioam6: a fix for an out-of-bounds access in skb_get_tx_queue when is_input is true, caused by a RX->TX queue-mapping mismatch (ingress device having more RX queues than egress TX queues). The issue could access dev->_tx[] beyond its bounds. A lock around qdi...
