CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-53046 Denial-of-service (NULL-pointer dereference / use-after-free) in the Linux kernel's in-kernel SMB3 server (ksmbd) affects systems that offload SMB3 message encryption to asynchronous hardware crypto engines such as the Qualcomm Crypto Engine (QCE). ksmbd_crypt_message() installs a NULL completion callback and misinterprets the -EINPROGRESS return from async AEAD requests as a fatal error, freeing the request while the hardware DMA is still running so the later qce_skcipher_done() callback dereferences freed memory and crashes the kernel. There is no public exploit identified at time of analysis, it is not in CISA KEV, and EPSS is low (0.18%, 8th percentile), consistent with the narrow hardware/configuration prerequisites despite the NVD CVSS of 9.8. CRITICAL 9.8 0.2% 49
CVE-2026-64188 Use-after-free in the Linux kernel's Qualcomm rmnet networking driver allows a local attacker with low privileges to escalate to kernel-level code execution. The flaw occurs when the rmnet endpoint is freed while still being referenced by concurrent receive path handlers, leading to memory corruption. No active exploitation or public exploit code has been identified, but the high CVSS score reflects a significant local privilege escalation risk. HIGH 7.8 0.2% 39
CVE-2026-43347 Memory corruption in Linux kernel on Qualcomm Monaco-based ARM64 platforms causes kernel crashes through synchronous external aborts when accessing hypervisor-owned memory incorrectly marked as conventional RAM. The firmware's EFI memory map only reserves 288 KiB of a 512 KiB Gunyah hypervisor metadata region (0x91a80000-0x91afffff), leaving 224 KiB exploitable for triggering fatal aborts. Patches available for stable branches 6.18.24, 6.19.14, and 7.0 series. EPSS exploitation probability is very low (0.02%, 4th percentile) with no known active exploitation or public POC, indicating limited real-world threat despite CVSS 7.5 rating. HIGH 7.5 0.0% 38
CVE-2026-64550 Out-of-bounds read in the Qualcomm rmnet (Rmnet Multiplexing and Aggregation Protocol) driver of the Linux kernel allows a local attacker to read kernel slab memory beyond frame boundaries by injecting a short MAP frame while ingress deaggregation is disabled. The no-aggregation ingress path skipped the length validation performed on the aggregated path, so the parser dereferenced the MAP header and checksum trailer using the on-wire pkt_len without verifying skb->len. No public exploit has been identified at time of analysis, and the low EPSS score (0.18%, 7th percentile) reflects the local-only, niche-driver nature of the flaw rather than widespread mass exploitation. HIGH 7.3 0.2% 37
CVE-2026-46055 Out-of-bounds read in the Linux kernel's AppArmor LSM subsystem (security/apparmor/match.c) allows a local low-privileged user to trigger a KASAN slab-out-of-bounds read via the mount() syscall on kernels 7.0 through 7.0.3 and 7.1-rc1. The flaw stems from a missing string terminator that causes aa_dfa_match() to read past the end of an 8KB kmalloc buffer when processing mount path strings, resulting in potential information disclosure and system instability (denial of service). No public exploit identified at time of analysis, and EPSS probability is negligible at 0.02%. HIGH 7.1 0.0% 36
CVE-2026-64100 Deadlock in the Linux kernel's drm/msm (Qualcomm Snapdragon GPU) shrinker causes full kernel hang under memory reclaim pressure. The circular lock dependency arises when the kswapd0 thread holds fs_reclaim and the MSM gem shrinker calls dma_resv_lock(), which internally attempts to re-acquire fs_reclaim - producing a ABBA deadlock that renders the system unresponsive. Kernels in the affected range on Snapdragon-based hardware (Linux 6.17 through pre-patch 7.0.x and 6.18.x) are vulnerable; no public exploit code exists and no active exploitation has been confirmed. MEDIUM 5.5 0.2% 28
CVE-2026-53339 NULL pointer dereference in the Linux kernel's Qualcomm Camera Control Interface (CCI) i2c driver crashes the kernel during driver removal on boards where only one of the two available I2C masters is initialized. Triggering device unbinding or module unloading on affected Qualcomm hardware configurations causes cci_remove() to call cci_halt() for both masters, dereferencing an uninitialized completion pointer for the disabled master and producing a kernel panic. No public exploit exists and EPSS is at the 6th percentile, indicating no meaningful exploitation activity; impact is limited to availability via local denial of service on specific Qualcomm SoC configurations. MEDIUM 5.5 0.2% 28
CVE-2026-43412 NULL pointer dereference in the Linux kernel's ASoC QCOM QDSP6 subsystem crashes systems built on Qualcomm SA8775P and SC8280XP SoCs during ADSP protection-domain restart cycles. The crash occurs because the q6apm-audio .remove callback prematurely deletes Runtime Descriptions (RTDs) containing q6apm DAI components during ASoC teardown, leaving those components still linked to the sound card and triggering a kernel oops on the subsequent rebind. Impact is limited to availability (kernel panic/denial of service); no public exploit has been identified at time of analysis, and EPSS at 0.02% reflects very low widespread exploitation probability. MEDIUM 5.5 0.0% 28
