CVE-2026-97945

The Linux kernel contains a vulnerability in x86 memory management where PMD-mapped Huge Transparent Pages (THP) can experience data loss. The root cause is that pmd_modify() incorrectly masks out the hardware dirty bit (_PAGE_DIRTY). This causes the kernel to lose the dirty state of a page when ...

CVE-2026-97943

The Linux kernel contains a vulnerability in the x86 architecture's Change Page Attributes (CPA) mechanism. Specifically, the cpa_collapse_large_pages() function can collapse kernel page table entries into huge page table entries and free the old page tables without holding necessary locks. This ...

CVE-2026-97942

The Linux kernel contains a vulnerability in the x86 alternatives patching code where a race condition between text poking and change_page_attr (CPA) can occur. If vmalloc_to_page() fails due to this race, it can result in the collapsing of page tables or the breaking of PMD hugepages . This issu...

CVE-2026-97941

A race condition exists in the Linux kernel memory management system within mm/slab. The __slab_try_return_freelist() function incorrectly assumed that no objects were freed to a slab if slab->freelist was NULL and cmpxchg succeeded. This oversight leads to a classic ABA problem where a slab c...

CVE-2026-97939

The Linux kernel is affected by a vulnerability where a netadmin in a user+net namespace could create numerous IPv4 and IPv6 multicast routing tables using MRT_TABLE and MRT6_TABLE. Because these mr_table objects were not charged to memcg , the host's unreclaimable slab would grow proportionally ...

CVE-2026-97940

The Linux kernel is affected by a Use-After-Free (UAF) vulnerability in the ipv6 component. The issue arises because ipv6_route_iter_active() incorrectly treats a walker in FWS_U at the table root as already unlinked. This allows fib6_del_route() to move a still-linked walker into that state when...

CVE-2026-97938

The Linux kernel contains a use-after-free race condition involving the cad_pid struct pid pointer. The issue occurs because proc_do_cad_pid() reads the pointer and passes it to pid_vnr() without protecting its lifetime; a concurrent writer can replace the pointer and drop the reference before th...

CVE-2026-97937

The Linux kernel contains a vulnerability in ftrace where the child function graph state is not initialized early enough during a fork operation. Specifically, dup_task_struct() copies the parent's task_struct including the ret_stack. Because ftrace_graph_init_task() currently runs after copy_exe...

CVE-2026-97936

The Linux kernel contains a memory corruption vulnerability in the tracing subsystem. The event_hist_trigger() function performs an unbounded memcpy when handling the histogram stacktrace modifier, using a count directly from the event data. This allows for an out-of-bounds write that can overwri...

CVE-2026-97935

The Linux kernel contains a slab-use-after-free vulnerability in the tracing subsystem. The issue occurs because hist_register_trigger() adds a histogram trigger to the global named_triggers list before validating the trace clock. If the clock string is unknown, tracing_set_clock() fails, causing...

CVE-2026-97934

The Linux kernel is vulnerable to memory corruption within the tracing subsystem. The issue arises because generic fields like "STACKTRACE" are mapped to placeholders instead of NULL by parse_field() . Consequently, create_hist_field() interprets data from the common_type field as an offset, lead...

CVE-2026-97933

The Linux kernel is vulnerable to a use-after-free race condition within the tracing subsystem. When a tracer option file is opened, the system uses a descriptor pointing to an element on the trace_array's topts array to increment the trace_array's reference counter. However, a race condition exi...

CVE-2026-97932

A vulnerability exists in the Linux kernel tracing subsystem where the enable_event trigger defers trace_event_put_ref() to the trigger free kthread. However, the trace_event_file can be freed prematurely when the instance is removed, leading to a use-after-free condition. The fix involves keepin...

CVE-2026-97931

The Linux kernel contains a vulnerability in the ALSA subsystem where the hwdep mmap callback fails to clear the VM_MAYWRITE flag on read-buffer mappings created with PROT_READ . This allows a process capable of opening the hwdep node with O_RDWR to use mprotect() to escalate permissions and make...

CVE-2026-97929

The Linux kernel contains a vulnerability in the ALSA: usbusx2y driver within the i_usx2y_in04_int() function. The driver fails to validate urb->actual_length , allowing a malfunctioning device to trigger a short transfer. This causes the handler to process uninitialized heap data from the kma...

CVE-2026-97930

The Linux kernel contains a vulnerability in the ALSA: usbusx2y component due to an array size mismatch between in04_last and in04_buf. Specifically, in04_last is declared as 24 bytes, while in04_buf is allocated as 21 bytes. This causes a buffer over-read in the i_usx2y_in04_int() function durin...

CVE-2026-97928

The Linux kernel contains a vulnerability in the drm/amdgpu driver where the amdgpu_ttm_map_buffer() function incorrectly forces a VMID 0 flush when performing a clear-on-release on VRAM . Because VRAM is accessed via a direct memory controller (MC) address without a programmed GART window , this...

CVE-2026-97927

The Linux kernel contains a vulnerability in the ufs filesystem where ufs_fill_super() installs the root dentry before successfully loading cylinder group structures for writable mounts. If ufs_read_cylinder_structures() fails, the error path frees the in-core superblock information and sets sb-&...

CVE-2026-97926

The Linux kernel contains a vulnerability in the ufs filesystem where ufs_read_cylinder() copies cylinder group index and rotor positions from on-disk groups into cache without validation. A crafted image can set these values to trigger out-of-bounds access during allocation or free operations. S...

CVE-2026-97925

A race condition exists in the Linux kernel during the replacement of a broadcast device . The issue occurs because tick_install_broadcast_device() is not serialized against concurrent tick broadcast operations. Specifically, a race between __tick_broadcast_oneshot_control() and tick_install_broa...
