EUVD-2026-58992

In the Linux kernel, the following vulnerability has been resolved: fhandle: reject detached mounts in capablewrtmount The recent fhandle RCU fix moved the mount namespace capability check into capablewrtmount, so a non-NULL mntnamespace survives the nscapable dereference. The helper still assume...

EUVD-2026-58986

In the Linux kernel, the following vulnerability has been resolved: riscv: probes: save original sp in rethook trampoline Reading a word from the stack in a kretprobe crashes a risc-v kernel. $ cd /sys/kernel/tracing/ $ echo 'r nttywrite $stack0' dynamicevents $ echo 1 events/kprobes/enable Unabl...

CVE-2026-72028

CVE-2026-72028 – Linux kernel (riscv) Root cause: In the riscv rethook trampoline path used by kprobes/kretprobe, the original stack pointer (sp) was not saved. The trampoline decremented sp for its local stack and did not preserve the original sp value when saving registers in struct pt_regs, le...

CVE-2026-72023 octeontx2-pf: fix SQB pointer leak on init failure

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: fix SQB pointer leak on init failure otx2inithwresources initializes SQ aura and pool resources before several later setup steps. On failure, errfreesqptrs only frees SQB pages, leaving the per-SQ sqbptrs arrays...

CVE-2026-72023

CVE-2026-72023 affects the Linux kernel’s octeontx2-pf driver. otx2_init_hw_resources() allocates SQ aura/pool resources before later setup steps, and on failure err_free_sq_ptrs frees only SQB pages, leaving per-SQ sqb_ptrs behind. The documented fix uses otx2_free_sq_res() for the SQ unwind pat...

EUVD-2026-59115

In the Linux kernel, the following vulnerability has been resolved: cpu/hotplug: Fix NULL kobject warning in cpuhpsmtenable On arm64, when booting with maxcpus greater than the number of present CPUs e.g., QEMU -smp cpus=4,maxcpus=8, some CPUs are marked as 'present' but have not yet been...

CVE-2026-72013

The CVE-2026-72013 entry concerns a Linux kernel RISCV NULL-pointer dereference in machine_kexec_prepare(), where image->segment[i].buf may be NULL and copied without validation. The NULL buf originates from ima_add_kexec_buffer() via kexec_add_buffer(), with kbuf.buffer NULL, leading to an un...

CVE-2026-72013 riscv: Prevent NULL pointer dereference in machine_kexec_prepare()

In the Linux kernel, the following vulnerability has been resolved: riscv: Prevent NULL pointer dereference in machinekexecprepare A NULL pointer dereference issue is noticed in riscv's machinekexecprepare, where image-segmenti.buf might be NULL and copied unchecked. The NULL buf comes from...

CVE-2026-72008 pmdomain: mediatek: Fix possible nullptr KP in HWV cleanup/on-check

In the Linux kernel, the following vulnerability has been resolved: pmdomain: mediatek: Fix possible nullptr KP in HWV cleanup/on-check Should probe fail for HWVOTER type power domains, this driver was unconditionally trying to perform cleanup for DIRECTCTL domains, but only after checking if the...

CVE-2026-72008

The CVE-2026-72008 entry describes a Mediatek power-domain issue in the Linux kernel where HWV domain probe/cleanup paths could perform power-domain checks incorrectly. Specifically, for HW_VOTER type domains, cleanup for DIRECT_CTL domains ran without confirming the target is powered on, using D...

In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: avoid full teardown before work setup in probe rt2x00libprobedev uses the full rt2x00libremovedev teardown for all probe failures. However, drvdata allocation and workqueue allocation can fail before intfwork,...

CVE-2026-68462

Summary of CVE-2026-68462 (Linux kernel, BPF): The issue arises in the verifier’s handling of buffer-pointer access (PTR_TO_TP_BUFFER and PTR_TO_BUF) where a constant negative offset could slip through after a pointer offset split (reg->var_off vs reg->off). Specifically, an access with reg...
