CVE-2023-52923

CVE-2023-52923 affects the Linux kernel netfilter nf_tables backend. The vulnerability arises from switching to the GC transaction API to replace the old gc API and busy-mark approach. No set elements are removed during async GC anymore; the _DEAD bit is set to hide elements from lookups, and asy...

CVE-2025-21659

CVE-2025-21659 covers a Linux kernel netdev issue where NAPI IDs were not namespaced because they were not exposed to user space before the netlink API. The vulnerability arises because netlink must ensure that a NAPI instance belongs to the same network namespace as the genl socket owner; otherw...

CVE-2025-21678

In CVE-2025-21678, Linux kernel gtp: Destroy device along with udp socket’s netns dismantle was fixed. The root cause was gtp_newlink() attaching the device to dev_net(dev) instead of src_net, which meant a UDP tunnel socket created in a different netns could leave the device alive in dev_net(dev...

CVE-2025-21664

CVE-2025-21664 affects the Linux kernel dm-thin component. Root cause: get_first_thin did a non-RCU-safe sequence (list_empty -> list_first) that could race with concurrent updates, risking dereferencing a stale/altered list head during process_deferred_bios flow and leading to a crash. Connec...

CVE-2025-21653

CVE-2025-21653 affects the Linux kernel net_sched flow classifier (net/sched/cls_flow.c). The vulnerability was due to missing validation of TCA_FLOW_RSHIFT, which could trigger undefined behavior (UB) and a shift-out-of-bounds on large 32-bit shifts, as shown by UBSAN. Connected advisories (Astr...

CVE-2025-21702

The CVE CVE-2025-21702 concerns a bug in Linux kernel pfifo_tail_enqueue where, when sch->limit == 0, a path can cause qlen to be increased to one even if a preceding drop would have kept it at zero. This leads to a mismatch where a parent qlen no longer equals the sum of its children’s qlen, ...

CVE-2025-21655

CVE-2025-21655 in the Linux kernel’s io_uring/eventfd was fixed by deferring the freeing of the io_eventfd object to an additional RCU grace period. The issue arose because io_eventfd_do_signal() is called from an RCU callback and, when the reference to the io_ev_fd drops to zero, the code attemp...

CVE-2025-21668

CVE-2025-21668 (Linux kernel) : A missing loop break in the imx8mp_blk_ctrl_remove path (imx8mp_blk_ctrl) allows the for loop to run out of bounds, potentially affecting system shutdown/reboot flows. The vulnerability is tied to the imx8mp domain handling in dev_pm_domain_detach during platform s...

The fix clamps the conntrack hashtable siz...

CVE-2024-57800

CVE-2024-57800 affects the Linux kernel in ALSA memalloc handling. When DMA API debugging is enabled, it may warn about a device driver failing to check a DMA address map, e.g. device address 0x00000000ffff0000, due to explicit address checks instead of using dma_mapping_error(). The documented f...

CVE-2025-21704

CVE-2025-21704 affects the Linux kernel USB CDC-ACM (cdc_acm) path. The root cause is improper handling of fragmented control transfers: if the first fragment is smaller than struct usb_cdc_notification, computing expected_size can underflow as fragments arrive, leading to memory corruption when ...

CVE-2024-57929

CVE-2024-57929 : In the Linux kernel, the vulnerability stems from dm-array: when dm_bm_read_lock() fails, a faulty dm_block pointer can be left behind, leading to a double release in dm_array_cursor_end() and a subsequent BUG_on in dm-bufio. The fix (as described in the CVE text) sets the cached...

CVE-2024-57904

CVE-2024-57904 affects the Linux kernel’s IIO subsystem for at91: the at91_ts_register path frees the wrong object during error handling. The code currently calls input_free_device() on st->ts_input, but the err path can run before iio_dev is assigned to st->ts_input. The fix is to call inp...

CVE-2025-21632

CVE-2025-21632: In the Linux kernel, a patch fixes shadow stack handling for x86 XSAVE state accessed via ptrace. Previously, regset get/set paths could be invoked with shadow stacks disabled (ARCH_SHSTK_SHSTK==0), causing get_xsave_addr() to return NULL and trigger a WARN_ON in ssp_get. The fix ...

CVE-2025-21679

CVE-2025-21679—Linux kernel (btrfs): The issue arises in get_canonical_dev_path() where d_path()’s possible error is not handled, causing an invalid memory access on the subsequent strscpy() call.
