CVE-2025-37955

CVE-2025-37955 concerns a memory leak in the Linux kernel virtio-net driver. The issue occurs on the error path of virtnet_xsk_pool_enable(), where xsk_buffs are not freed, leading to an unreferenced 2048-byte object in the xdp helper path. The backtrace points to virtnet_xsk_pool_enable and rela...

CVE-2025-37954

In the Linux kernel, the following vulnerability has been resolved: smb: client: Avoid race in opencacheddir with lease breaks A pre-existing valid cfid returned from findorcreatecacheddir might race with a lease break, meaning opencacheddir doesn't consider it valid, and thinks it's...

CVE-2025-37952 ksmbd: Fix UAF in __close_file_table_ids

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix UAF in closefiletableids A use-after-free is possible if one thread destroys the file via ksmbdclosefd while another thread holds a reference to it. The existing checks on fp-refcount are not sufficient to prevent this...

CVE-2025-37951

CVE-2025-37951 affects the Linux kernel DRM/V3D path. When a CL/CSD job times out, if the GPU progressed, the kernel may skip the reset, keeping the job running; however, timedout_job() removes the job from the pending list, so it may not be freed, causing a memory leak. A patch adds the job back...

CVE-2025-37951

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Add job to pending list if the reset was skipped When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the time...

CVE-2025-37948 arm64: bpf: Add BHB mitigation to the epilogue for cBPF programs

In the Linux kernel, the following vulnerability has been resolved: arm64: bpf: Add BHB mitigation to the epilogue for cBPF programs A malicious BPF program may manipulate the branch history to influence what the hardware speculates will happen next. On exit from a BPF program, emit the BHB...

CVE-2025-37948

CVE-2025-37948 affects the Linux kernel arm64 and is fixed by adding a BHB mitigation in the epilogue of BPF programs (cBPF) loaded via seccomp. The vulnerability arises when a classic cBPF program manipulates the branch history to influence speculative execution. The published details indicate t...

CVE-2025-37946

CVE-2025-37946 concerns the Linux kernel, specifically the s390 PCI subsystem. The issue arises from a duplicate pci_dev_put() in disable_slot() when a PF has child VFs, introduced during a change that added a lock to zpci_dev state. The extra pci_dev_put() can lead to a use-after-free if the pci...
