Use-after-free memory corruption in the Linux kernel's lpfc Fibre Channel driver exposes systems with Emulex/Broadcom FC HBAs to potential kernel-level code execution or denial of service. The flaw resides in the FLOGI and PLOGI ELS (Extended Link Services) failure-handling paths, where premature node (ndlp) deallocation races with pending dev-loss-evt work items, causing subsequent dereference of freed kernel memory. No public exploit has been identified and EPSS is extremely low at 0.03% (8th percentile), but the C:H/I:H/A:H impact potential in kernel space keeps this a meaningful priority for Fibre Channel-attached Linux environments. Multiple SUSE kernel advisories issued through 2025 confirm the patch has been backported to enterprise distributions.

Use-after-free in the Linux kernel's mac80211 wifi subsystem exposes wireless-enabled Linux systems to kernel memory corruption exploitable by adjacent-network unauthenticated attackers. The flaw in `ieee80211_vif_use_reserved_context()` allows a dangling `old_ctx` pointer to be dereferenced after it has been freed inside `ieee80211_vif_use_reserved_reassign()`, enabling heap corruption that could result in kernel panic or privilege escalation. Patch commits are available across nine upstream stable branches and are confirmed addressed by Red Hat (RHSA-2023:2951, RHSA-2023:2458) and multiple SUSE advisories; no public exploit code or CISA KEV listing has been identified at time of analysis.

Use-after-free in the Linux kernel's NFS server (NFSD) nfsd_file_put() routine allows a memory-corruption condition on hosts that export filesystems over NFS, because the code dereferences the file object @nf after nfsd_file_put_noref() may already have freed it. The flaw affects the in-kernel NFSD subsystem (regression present in 5.19-rc1 and backported stable trees) and can be reached by NFS clients interacting with an exported share, potentially yielding denial of service or, in a worst case, kernel memory disclosure or corruption. No public exploit is identified at time of analysis and the EPSS score is very low (0.04%), so this is a patch-and-move-on kernel hardening fix rather than an actively exploited threat.

Use-after-free in the Linux kernel's mt76 MediaTek WiFi driver exposes systems with MT76-series adapters to kernel memory corruption when a race condition between the TX scheduling worker thread and station lifecycle management is triggered from an adjacent network position. The mtxq->wcid pointer in mt76_txq_schedule is read without RCU protection while a concurrent sta_info_free call in the mac80211 subsystem invalidates it, confirmed by KASAN instrumentation in the CVE description. No active exploitation has been confirmed (absent from CISA KEV) and EPSS is extremely low at 0.01%, though the 8.8 CVSS score reflects the kernel-level impact potential of the underlying primitive.

Use-after-free in the Linux kernel TPM subsystem allows a local attacker to trigger kernel memory corruption by exploiting a reference counting defect in struct tpm_chip. The flaw manifests when a file descriptor to /dev/tpmrm is held open while the underlying TPM driver module (e.g., tpm_tis_spi) is unloaded, then a write is issued to that descriptor - causing tpm_common_write() to attempt a kobject_get() on an already-zeroed reference counter. No public exploit has been identified at time of analysis, and EPSS at 0.10% signals low opportunistic exploitation pressure.

Use-after-free in the Linux kernel ath11k Wi-Fi driver exposes systems with Qualcomm QCA6390 or WCN6855 chipsets to kernel memory corruption when a wireless station disconnects from an AP. A prior fix commit (b4a0f54156ac) intended to prevent firmware crashes inadvertently bypassed all peer delete cleanup, leaving peer->sta as a dangling pointer subsequently dereferenced by ath11k_dp_rx_update_peer_stats during monitoring ring timer processing - confirmed by KASAN in kernel 5.15. No active exploitation is confirmed (not in CISA KEV), with EPSS at just 0.05% (14th percentile), but the kernel-level UAF class can escalate from denial-of-service to privilege escalation in skilled hands.

This Use After Free vulnerability could allow attackers to access freed memory to execute arbitrary code or crash the application.
Use-after-free in the Linux kernel's ref_tracker subsystem exposes local low-privilege users to full kernel memory corruption during netdevice teardown. The flaw exists because ref_tracker_alloc() and ref_tracker_free() do not validate the dead status of a struct ref_tracker_dir after ref_tracker_dir_init() marks it as destroyed, allowing dev_put()/dev_hold() operations that fire too late in the netdevice dismantle sequence to access logically-freed memory. No public exploit exists and EPSS at 0.05% (14th percentile) confirms negligible real-world exploitation activity; active exploitation is not confirmed in CISA KEV.
Use-after-free in the Linux kernel's libfc Fibre Channel library within fc_exch_abts_resp() exposes systems on SAN fabrics to kernel memory corruption from unauthenticated adjacent-network attackers. The flaw arises because fc_exch_release(ep) can free the exchange object when its reference count reaches zero, yet subsequent code continues dereferencing ep - a classic CWE-416 pattern with C:H/I:H/A:H potential impact. Despite the CVSS 8.8 score, no public exploit code has been identified and the EPSS of 0.07% (20th percentile) reflects the niche Fibre Channel deployment context and the practical difficulty of reliable kernel UAF exploitation.
Use-after-free memory corruption in the Linux kernel Bluetooth subsystem's hci_send_acl function allows an adjacent unauthenticated attacker to corrupt kernel heap memory by triggering a specific Bluetooth PHY link disconnect sequence. The flaw occurs because HCI_EV_DISCONN_PHY_LINK_COMPLETE causes hci_conn_del to be invoked without first verifying conn->type is AMP_LINK, bypassing the hci_disconn_cfm upper-layer cleanup; the freed hci_chan object is then accessed by a userspace Bluetooth daemon via hci_send_acl, producing a confirmed KASAN use-after-free at offset +24 in a freed kmalloc-128 region. No public exploit identified at time of analysis; EPSS at 0.04% (12th percentile) indicates no observed widespread exploitation, though the zero-authentication adjacent-network attack surface is meaningful in Bluetooth-enabled environments.
Use-after-free in the Linux kernel networking stack (skbuff) corrupts memory when page_pool fragment recycling coalesces a cloned socket buffer, first observed as IOMMU faults during normal RX traffic on the HiSilicon hns3 driver. When two half-page fragments and a cloned skb are coalesced via skb_try_coalesce(), a plain page reference is taken instead of incrementing pp_frag_count, causing a page still owned by an in-flight RX descriptor to be freed early. Rated CVSS 9.8 by NVD, but EPSS is only 0.04% (14th percentile), no public exploit is identified at time of analysis, and it is not in CISA KEV.

Use-after-free in the Linux kernel's mac80211 wifi subsystem exposes wireless-enabled Linux systems to kernel memory corruption exploitable by adjacent-network unauthenticated attackers. The flaw in `ieee80211_vif_use_reserved_context()` allows a dangling `old_ctx` pointer to be dereferenced after it has been freed inside `ieee80211_vif_use_reserved_reassign()`, enabling heap corruption that could result in kernel panic or privilege escalation. Patch commits are available across nine upstream stable branches and are confirmed addressed by Red Hat (RHSA-2023:2951, RHSA-2023:2458) and multiple SUSE advisories; no public exploit code or CISA KEV listing has been identified at time of analysis.

Use-after-free in the Linux kernel's NFS server (NFSD) nfsd_file_put() routine allows a memory-corruption condition on hosts that export filesystems over NFS, because the code dereferences the file object @nf after nfsd_file_put_noref() may already have freed it. The flaw affects the in-kernel NFSD subsystem (regression present in 5.19-rc1 and backported stable trees) and can be reached by NFS clients interacting with an exported share, potentially yielding denial of service or, in a worst case, kernel memory disclosure or corruption. No public exploit is identified at time of analysis and the EPSS score is very low (0.04%), so this is a patch-and-move-on kernel hardening fix rather than an actively exploited threat.

Use-after-free in the Linux kernel TPM subsystem allows a local attacker to trigger kernel memory corruption by exploiting a reference counting defect in struct tpm_chip. The flaw manifests when a file descriptor to /dev/tpmrm is held open while the underlying TPM driver module (e.g., tpm_tis_spi) is unloaded, then a write is issued to that descriptor - causing tpm_common_write() to attempt a kobject_get() on an already-zeroed reference counter. No public exploit has been identified at time of analysis, and EPSS at 0.10% signals low opportunistic exploitation pressure.

Use-after-free in the Linux kernel ath11k Wi-Fi driver exposes systems with Qualcomm QCA6390 or WCN6855 chipsets to kernel memory corruption when a wireless station disconnects from an AP. A prior fix commit (b4a0f54156ac) intended to prevent firmware crashes inadvertently bypassed all peer delete cleanup, leaving peer->sta as a dangling pointer subsequently dereferenced by ath11k_dp_rx_update_peer_stats during monitoring ring timer processing - confirmed by KASAN in kernel 5.15. No active exploitation is confirmed (not in CISA KEV), with EPSS at just 0.05% (14th percentile), but the kernel-level UAF class can escalate from denial-of-service to privilege escalation in skilled hands.

Use-after-free in the Linux kernel's ref_tracker subsystem exposes local low-privilege users to full kernel memory corruption during netdevice teardown. The flaw exists because ref_tracker_alloc() and ref_tracker_free() do not validate the dead status of a struct ref_tracker_dir after ref_tracker_dir_init() marks it as destroyed, allowing dev_put()/dev_hold() operations that fire too late in the netdevice dismantle sequence to access logically-freed memory. No public exploit exists and EPSS at 0.05% (14th percentile) confirms negligible real-world exploitation activity; active exploitation is not confirmed in CISA KEV.
Use-after-free in the Linux kernel's libfc Fibre Channel library within fc_exch_abts_resp() exposes systems on SAN fabrics to kernel memory corruption from unauthenticated adjacent-network attackers. The flaw arises because fc_exch_release(ep) can free the exchange object when its reference count reaches zero, yet subsequent code continues dereferencing ep - a classic CWE-416 pattern with C:H/I:H/A:H potential impact. Despite the CVSS 8.8 score, no public exploit code has been identified and the EPSS of 0.07% (20th percentile) reflects the niche Fibre Channel deployment context and the practical difficulty of reliable kernel UAF exploitation.
Use-after-free memory corruption in the Linux kernel Bluetooth subsystem's hci_send_acl function allows an adjacent unauthenticated attacker to corrupt kernel heap memory by triggering a specific Bluetooth PHY link disconnect sequence. The flaw occurs because HCI_EV_DISCONN_PHY_LINK_COMPLETE causes hci_conn_del to be invoked without first verifying conn->type is AMP_LINK, bypassing the hci_disconn_cfm upper-layer cleanup; the freed hci_chan object is then accessed by a userspace Bluetooth daemon via hci_send_acl, producing a confirmed KASAN use-after-free at offset +24 in a freed kmalloc-128 region. No public exploit identified at time of analysis; EPSS at 0.04% (12th percentile) indicates no observed widespread exploitation, though the zero-authentication adjacent-network attack surface is meaningful in Bluetooth-enabled environments.
Use-after-free in the Linux kernel networking stack (skbuff) corrupts memory when page_pool fragment recycling coalesces a cloned socket buffer, first observed as IOMMU faults during normal RX traffic on the HiSilicon hns3 driver. When two half-page fragments and a cloned skb are coalesced via skb_try_coalesce(), a plain page reference is taken instead of incrementing pp_frag_count, causing a page still owned by an in-flight RX descriptor to be freed early. Rated CVSS 9.8 by NVD, but EPSS is only 0.04% (14th percentile), no public exploit is identified at time of analysis, and it is not in CISA KEV.
