CVE-2025-37954 – smb: client: Avoid race in open_cached_dir with lease breaks
https://notcve.org/view.php?id=CVE-2025-37954
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: smb: client: Avoid race in open_cached_dir with lease breaks A pre-existing valid cfid returned from find_or_create_cached_dir might race with a lease break, meaning open_cached_dir doesn't consider it valid, and thinks it's newly-constructed. This leaks a dentry reference if the allocation occurs before the queued lease break work runs. Avoid the race by extending holding the cfid_list_lock across find_or_create_cached_dir and when the res... • https://git.kernel.org/stable/c/2ed98e89ebc2e1bc73534dc3c18cb7843a889ff9 •

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: sch_htb: make htb_deactivate() idempotent Alan reported a NULL pointer dereference in htb_next_rb_node() after we made htb_qlen_notify() idempotent. It turns out in the following case it introduced some regression: htb_dequeue_tree(): |-> fq_codel_dequeue() |-> qdisc_tree_reduce_backlog() |-> htb_qlen_notify() |-> htb_deactivate() |-> htb_next_rb_node() |-> htb_deactivate() For htb_next_rb_node(), after calling the 1st htb_deactivate(), the... • https://git.kernel.org/stable/c/73cf6af13153d62f9b76eff422eea79dbc70f15e •

CVE-2025-37952 – ksmbd: Fix UAF in __close_file_table_ids
https://notcve.org/view.php?id=CVE-2025-37952
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix UAF in __close_file_table_ids A use-after-free is possible if one thread destroys the file via __ksmbd_close_fd while another thread holds a reference to it. The existing checks on fp->refcount are not sufficient to prevent this. The fix takes ft->lock around the section which removes the file from the file table. This prevents two threads acquiring the same file pointer via __close_file_table_ids, as well as the other functions ... • https://git.kernel.org/stable/c/fec1f9e9a650e8e7011330a085c77e7bf2a08ea9 •

CVE-2025-37951 – drm/v3d: Add job to pending list if the reset was skipped
https://notcve.org/view.php?id=CVE-2025-37951
20 May 2025 — 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 timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `... • https://git.kernel.org/stable/c/5235b56b7e5449d990d21d78723b1a5e7bb5738e •

CVE-2025-37947 – ksmbd: prevent out-of-bounds stream writes by validating *pos
https://notcve.org/view.php?id=CVE-2025-37947
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ksmbd: prevent out-of-bounds stream writes by validating *pos ksmbd_vfs_stream_write() did not validate whether the write offset (*pos) was within the bounds of the existing stream data length (v_len). If *pos was greater than or equal to v_len, this could lead to an out-of-bounds memory write. This patch adds a check to ensure *pos is less than v_len before proceeding. If the condition fails, -EINVAL is returned. In the Linux kernel, the f... • https://git.kernel.org/stable/c/7f61da79df86fd140c7768e668ad846bfa7ec8e1 •
