CVE-2026-43432

CVE-2026-43432 relates to the Linux kernel USB xHCI driver. The error path in usb/xhci_disable_slot() previously freed only the command structure (via kfree), leaking the associated completion structure. The patch changes the code to call xhci_free_command() , which frees both the command structu...

CVE-2026-43415

CVE-2026-43415 describes a race in the Linux kernel’s UFS host controller driver (scsi: ufs: core) during UFS suspend. The issue arises because cancel_delayed_work_sync() is invoked after ufshcd_vops_suspend(..., POST_CHANGE), allowing ufshcd_rtc_work() to race with suspend operations and potenti...

CVE-2026-43411

CVE-2026-43411: Linux kernel TIPc divide-by-zero in tipc_sk_filter_connect() when conn_timeout is 0–3, triggering a kernel oops/panic on certain overload retry paths. The public docs state that an attacker can set conn_timeout via setsockopt(TIPC_CONN_TIMEOUT) to values below 4, causing delay %= ...

CVE-2026-43409

CVE-2026-43409 affects the Linux kernel kprobes subsystem: when ftrace is disabled due to errors, removing a module that uses kprobes can crash the system because kprobes_ftrace_disabled is not correctly handled. Root cause: kprobe_ftrace_disabled flag mishandling in __disarm_kprobe_ftrace(). Mit...

CVE-2026-43389 mm: memfd_luo: always dirty all folios

In the Linux kernel, the following vulnerability has been resolved: mm: memfdluo: always dirty all folios A dirty folio is one which has been written to. A clean folio is its opposite. Since a clean folio has no user data, it can be freed under memory pressure. memfd preservation with LUO saves t...

CVE-2026-43385

The CVE-2026-43385 entries describe a race condition in the Linux kernel’s rcu_tasks grace-period handling inside napi_threaded_poll_loop when threaded busypoll is enabled. The issue can cause a stall/hang (DoS-like impact) as rcu_softirq_qs_periodic last_qs could be reset incorrectly, preventing...

CVE-2026-43363

CVE-2026-43363 concerns the Linux kernel x86 APIC subsystem. If, on resume from s2ram (S2/S3 wake), firmware re-enables x2APIC mode after the kernel has booted with x2APIC disabled, the system can run with x2APIC hardware but the kernel uses the xapic interface, leading to hangs. The issue is cau...

CVE-2026-43359 btrfs: fix transaction abort on set received ioctl due to item overflow

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix transaction abort on set received ioctl due to item overflow If the set received ioctl fails due to an item overflow when attempting to add the BTRFSUUIDKEYRECEIVEDSUBVOL we have to abort the transaction since we did...

CVE-2026-43358

CVE-2026-43358 affects the Linux kernel's btrfs filesystem. The vulnerability is a missing RCU unlock in the error path of try_release_subpage_extent_buffer(), where rcu_read_lock() should be held before exiting the loop because an rcu_read_unlock() occurs past the loop. The issue was identified ...
