In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid NULL deref of conn-lnk in smcmsgevent tracepoint The smcmsgevent tracepoint class, shared by smctxsendmsg and smcrxrecvmsg, unconditionally dereferences smc-conn.lnk: stringname, smc-conn.lnk-ibname conn-lnk is onl...

EUVD-2026-38708

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL pointer dereference in bpfskstorageclone and diag paths bpfselemunlinknofail sets SDATAselem-smap to NULL before removing the selem from the storage hlist. A concurrent RCU reader in bpfskstorageclone can observe th...

In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: handle forward allocation error batadvdatforwarddata calls pskbcopyforclone to duplicate an skb for each DHT candidate, but does not check the return value before passing it to batadvsendskbprepareunicast4addr...

EUVD-2026-38716

In the Linux kernel, the following vulnerability has been resolved: batman-adv: v: stop OGMv2 on disabled interface When a batadvhardiface is disabled, its meshiface pointer is set to NULL. However, batadvvogmsendmeshif may still dispatch OGMs via batadvvogmqueueonif for interfaces that have sinc...

CVE-2026-52941

The CVE-2026-52941 issue affects the Linux kernel’s SMC tracepoints. The smc_msg_event tracepoint unconditionally dereferences smc->conn.lnk->ibname, causing a NULL dereference when conn->lnk is NULL on SMC-D (while it is set for SMC-R). This can crash the first sendmsg()/recvmsg() on an...

CVE-2026-52939

Linux kernel vulnerability CVE-2026-52939 affects RDS over InfiniBand. A NULL dereference can occur in rds_ib_send_cqe_handler() when handling masked atomic completions, due to rds_ib_send_unmap_op() not covering masked opcodes. The issue occurs because masked atomic opcodes (IB_WR_MASKED_ATOMIC_...

CVE-2026-52938

The CVE-2026-52938 issue concerns a NULL pointer dereference in the Linux kernel BPF storage paths. The root cause is that bpf_selem_unlink_nofail() sets selem->smap to NULL, and a concurrent reader in bpf_sk_storage_clone() may observe the element still on the list with a NULL smap, leading t...

CVE-2026-52925

The CVE-2026-52925 entry relates to the Linux kernel VRF handling. The vulnerability arose from a race where an RCU reader identifying a net device as a VRF port could dereference l3mdev operations of a master device (e.g., a bridge) after netdev_master_upper_dev_get_rcu() returned it as a VRF de...

CVE-2026-52922

The CVE-2026-52922 entry describes a Linux kernel issue in batman-adv (dat handling) where batadv_dat_forward_data() duplicates skb with pskb_copy_for_clone() but ignores its return value. If allocation fails, batadv_send_skb_prepare_unicast_4addr() dereferences a NULL skb, causing a NULL pointer...

CVE-2026-52913

The CVE-2026-52913 issue affects the Linux kernel batman-adv subsystem where, after a batadv_hard_iface is disabled and its mesh_iface becomes NULL, batadv_v_ogm_send_meshif() can still queue OGMs via batadv_v_ogm_queue_on_if() for interfaces that lost their mesh_iface. This leads to a NULL point...
