Use-after-free memory corruption in the Linux kernel's btmtksdio Bluetooth SDIO driver allows adjacent, unauthenticated attackers within Bluetooth range to read freed kernel heap memory and potentially achieve kernel-level code execution or system crash on devices equipped with MediaTek SDIO Bluetooth chipsets. The vulnerability originates in btmtksdio_recv_event(), where the driver continues accessing an skb buffer after transferring ownership to the HCI stack - a flaw confirmed by an in-tree KASAN trace. No public exploit has been identified and EPSS exploitation probability is 0.04%, but the theoretical kernel impact warrants patching on affected hardware.
Use-after-free race condition in the Linux kernel's mt76 MediaTek wireless driver allows an adjacent network attacker to potentially corrupt kernel memory during station removal. When a wireless station is disconnected while concurrent TX activity is ongoing, an skb can be enqueued into the status-tracking IDR after that IDR has already been torn down, leaving the wcid pointer dangling in the status poll list. EPSS is 0.04% (11th percentile) and no public exploit or CISA KEV listing exists, but the kernel-level use-after-free carries high theoretical C/I/A impact per CVSS 8.8.
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 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 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.
