CVE-2026-72473

Affected software: Linux kernel (xprtrdma RPC path). Vulnerability: a race/lifecycle issue in rl_kref and send-side references within rpcrdma/xprt_rdma code caused improper freeing of request buffers while a DMA operation could still be active. Root cause: rl_kref previously gated two lifetimes w...

CVE-2026-72461

Vulnerability CVE-2026-72461 affects the Linux kernel with AppArmor: a refcount leak in updating the sk_ctx. Root cause: update_sk_ctx() transfers the plabel reference but also unconditionally releases it in the caller; the fix is to obtain a proper reference and avoid double-free. Affected compo...

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix potential UAF in MLD delayed work A race condition exists between device teardown and incoming MLD query processing, leading to a Use-After-Free in the MLD delayed work. During device destruction, the primary...

CVE-2026-72323

CVE-2026-72323 — Linux kernel igmp UAF vulnerability : A race between device teardown (inetdev_destroy) and IGMP query processing (igmp_rcv) can cause a Use-After-Free in the IGMP timer callback when the timer is re-armed. The in_device memory is freed via RCU after its refcount reaches 0, but ig...

EUVD-2026-59220

In the Linux kernel, the following vulnerability has been resolved: ipv4: igmp: Fix potential memory leaks in igmpmodtimer and igmpstoptimer When a timer is deleted and not re-armed in igmpmodtimer, or stopped in igmpstoptimer, the code currently decrements the reference counter of the multicast...

CVE-2026-72321

CVE-2026-72321 affects the Linux kernel’s IGMP timer handling (ipv4: igmp). The root cause is a memory leak when deleting or stopping timers in igmp_mod_timer() and igmp_stop_timer(): refcount_dec(&im->refcnt) can drop the group entry im to zero on an RC reader path, leaving the im object leak...

CVE-2026-72317 SUNRPC: pin upper rpc_clnt across the TLS connect_worker

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: pin upper rpcclnt across the TLS connectworker The TLS connect path has a use-after-free: nothing pins the upper rpcclnt across the delayed connectworker. xsconnect stores task-tkclient in sockxprt::clnt as a raw pointer...

CVE-2026-72317

In the Linux kernel SUNRPC TLS connect path, a use-after-free occurs because upper rpc_clnt is not pinned across the delayed TLS connect_worker. The TLS handshake worker xs_tcp_tls_setup_socket() reads saved fields from a freed rpc_clnt when a handshake fails, leading to a refcount underflow. The...

CVE-2026-72308

CVE-2026-72308 affects the Linux kernel’s mlxsw port code, where mlxsw_sp_port_lag_join() can leak a refcount if mlxsw_sp_port_lag_index_get() fails. The issue arises when an error path bypasses the standard cleanup that releases the lag reference with mlxsw_sp_lag_put(), leading to a single miss...
