CVE-2026-93285

The Linux kernel addresses a vulnerability in the f2fs file system. The fix involves embedding f2fs_gc_kthread directly into f2fs_sb_info instead of allocating it dynamically. This structural change simplifies lifetime management and is intended to resolve race conditions that occur during teardo...

CVE-2026-93247

The Linux kernel contains a NULL pointer dereference vulnerability within the Bluetooth management subsystem. The issue arises because the uuid_count member of struct discovery_state is accessed and modified without proper locking, creating a race condition during hci_update_passive_scan_sync. If...

CVE-2026-93239 arm64: mm: Fix the lockless page-table walk in show_pte()

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Fix the lockless page-table walk in showpte showpte walks page tables locklessly and can run with interrupts enabled. A concurrent teardown can free a table page while it is being walked. It can also clear a parent ent...

CVE-2026-93229

The Linux kernel is affected by a vulnerability in the nfsd component. Specifically, the hand-rolled seqcount-like protocol in nfsd_nl_rpc_status_get_dumpit() lacks a read memory barrier (smp_rmb) before its second counter check. On weakly-ordered architectures such as ARM and POWER , the CPU may...

EUVD-2026-86225

In the Linux kernel, the following vulnerability has been resolved: signal: avoid shared siginfo namespace rewrites sendsignallocked rewrites sender ids for the target namespace. Group sends reuse the same siginfo, so one recipient can affect the next. Copy the siginfo before changing it...

CVE-2026-93222

The Linux kernel contains a vulnerability where the send_signal_locked() function rewrites sender IDs for the target namespace. Because group sends reuse the same siginfo structure, one recipient can inadvertently affect the next. The issue is resolved by copying the siginfo before modification. ...

CVE-2026-93221

The Linux kernel is vulnerable to a race condition in the nfsd component due to a lack of serialization when accessing boolean fields in nfsd_net. Specifically, the nfsd4_end_grace() function uses a plain boolean for grace_ended, allowing concurrent paths—such as the laundromat path and the RECLA...
