CVE-2026-93149

This Linux kernel vulnerability affects the mac80211_hwsim (hardware-simulated WiFi) driver. In mac80211_hwsim_stop(), a race condition exists between the skb_queue_empty() check and the subsequent skb_dequeue() call. Because TX status handling can remove a pending frame under the queue lock betw...

CVE-2026-93148

CVE-2026-93148 is a Linux kernel vulnerability in the BPF subsystem . The root cause lies in how BTF struct walks relax the struct-size check for accesses through a trailing flexible array. While valid for ordinary BTF type walking, PTR_TO_BTF_ID | MEM_ALLOC values point to objects allocated with...

CVE-2026-93146

CVE-2026-93146 is a Linux kernel vulnerability in the time/namespace subsystem. The function proc_timens_set_offset() validates the tv_sec field but fails to validate that tv_nsec is within the required range [0, NSEC_PER_SEC-1] before passing it to timespec64_add() , which expects normalized val...

CVE-2026-93147

CVE-2026-93147 affects the Linux kernel on the s390 architecture within the BPF (Berkeley Packet Filter) subsystem. The root cause is that the ly instruction loads the 32-bit value cpu_nr into the 64-bit register BPF_REG_0 without zeroing the upper 32 bits, leaving stale data that can corrupt sub...

CVE-2026-93145

A vulnerability in the Linux kernel Qualcomm GDSC (Generic Dynamic Switch Controller) clock driver. The function gdsc_unregister() removed the OF provider entry and tore down parent/subdomain wiring but never called pm_genpd_remove() on the individual generic_pm_domain structures registered by gd...

CVE-2026-93143

CVE-2026-93143 affects the Linux kernel's staging: media: ipu7 driver. The vulnerability is a pm_runtime refcount leak in the ipu7_resume() function: when pm_runtime_get_sync() is called and the subsequent runtime PM resume fails, the usage count remains incremented but the error path returns wit...

CVE-2026-93144

CVE-2026-93144 affects the Linux kernel BPF subsystem, specifically the check_ptr_to_btf_access() path. The root cause is that program-type btf_struct_access callbacks can validate writes before the default BTF access path rejects non-read accesses, bypassing the read-only policy enforced for unt...

CVE-2026-93142

CVE-2026-93142 affects the Linux kernel 's RCAR thermal driver (thermal/drivers/rcar). The root cause is an error pointer dereference of priv->zone: the code calls thermal_zone_device_enable() before verifying that thermal_zone_device_register_with_trips() succeeded, so a failed registration l...

CVE-2026-93141

CVE-2026-93141 is a double-free vulnerability in the Linux kernel's Renesas R8A66597 USB gadget driver (r8a66597). When usb_add_gadget_udc() fails during device probe, the ep0_req request structure is freed in the err_add_udc error path and then freed a second time in clean_up2, leading to a doub...

CVE-2026-93140

CVE-2026-93140 affects the Linux kernel's UDF filesystem . When an I/O error occurs while writing the Logical Volume Integrity Descriptor (LVID) buffer, the block layer clears the BH_Uptodate flag, even though the in-memory data remains valid. Subsequent calls to udf_open_lvid() or udf_sync_fs() ...

CVE-2026-93139

CVE-2026-93139 affects the Linux kernel's amdgpu driver , specifically the MES (Micro-Engine Scheduler) component. The root cause is a loop in the hung_queue_db_array that iterated only AMDGPU_MAX_MES_PIPES times, leaving entries uninitialized for multi-XCC GPUs. This results in null pointer dere...

CVE-2026-93138

CVE-2026-93138 is a memory ordering race in the Linux kernel's BPF subsystem, specifically in bpf_get_btf_vmlinux(). The function lazily parses the vmlinux BTF under a mutex but publishes the resulting pointer via a plain store and reads it via a plain lockless load. On weakly-ordered architectur...

CVE-2026-93137

CVE-2026-93137 is a use-after-free in the Linux kernel's BPF subsystem, specifically in bpf_find_vma(). The function reads task->mm and calls mmap_read_trylock(mm) without holding a reference on the mm_struct. When operating on a foreign task , a concurrent exit_mm() can free the mm_struct bet...

CVE-2026-93136

CVE-2026-93136 affects the Linux kernel's MHI (Modem Host Interface) bus endpoint driver (bus: mhi: ep). The vulnerability is a device reference count leak in the error path of MHI device creation. When dev_set_name() or device_add() fails during device creation, the error path incorrectly drops ...

CVE-2026-93134

Linux kernel printk console subsystem is affected by a possible use-after-free in console_flush_one_record(). When emitting a record via legacy printing, a handover to another legacy printing context may release the console SRCU read lock, leaving the @con pointer invalid. The function failed to ...

CVE-2026-93135

CVE-2026-93135 is a vulnerability in the Linux kernel BPF subsystem affecting architectures that implement bpf_jit_inlines_helper_call() (e.g., LoongArch, ARM64, RISC-V ). When the verifier skips rewriting the helper call offset (insn->imm) because it expects the JIT to inline the helper, the ...

CVE-2026-93133

This CVE affects the Linux kernel ACPI RISC-V subsystem, specifically the riscv_acpi_add_prt_dep() function. The root cause is that the acpi_get_handle() call can fail, leaving the link_handle variable uninitialized , which could lead to undefined behavior when the variable is subsequently used. ...

CVE-2026-93131

CVE-2026-93131 affects the Linux kernel's platform/x86/dell-privacy driver . The vulnerability is a race condition caused by accessing priv->features_present without holding the list mutex, which allows the priv structure to be freed while still in use (use-after-free). The fix ensures the lis...

CVE-2026-93132

This vulnerability affects the Linux kernel 's ACPI RISC-V subsystem, specifically the riscv_acpi_add_prt_dep() function. The root cause is that the loop's error conditions are handled by continue statements that skip the entry pointer update to the next entry, resulting in dubious or incorrect p...

CVE-2026-93130

CVE-2026-93130 affects the Linux kernel's dell-wmi-base platform driver (under platform/x86). The root cause is a resource leak : when the module load fails, the SMBIOS request and the privacy driver are not properly cleaned up. The fix ensures proper release of these resources on the failure pat...
