CVE-2026-43090

CVE-2026-43090 concerns a Linux kernel memory-leak in the XFRM subsystem. The root cause is a double call to xfrm_pol_hold_rcu() inside xfrm_migrate_policy_find(), even though the lookup function already returns a policy with a held reference. This leads to a refcount imbalance and memory leak of...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003221 advisory. net/xfrm/xfrmpolicy.c in the Linux kernel through 4.12.3, when CONFIGXFRMMIGRATE is enabled, does not ensure that the dir value of xfrmuserpolicyid is XFRMPOLICYMAX ...

kernel: Out-of-bounds access via an XFRM_MSG_MIGRATE xfrm Netlink message

The xfrmmigrate function in the net/xfrm/xfrmpolicy.c file in the Linux kernel built with CONFIGXFRMMIGRATE does not verify if the dir parameter is less than XFRMPOLICYMAX. This allows a local attacker to cause a denial of service out-of-bounds access or possibly have unspecified other impact by...
