https://notcve.org/view.php?id=CVE-2025-37948
20 May 2025 — 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 mititgation sequence. This is only applied for 'classic' cBPF programs that are loaded by seccomp.

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: HID: pidff: Make sure to fetch pool before checking SIMULTANEOUS_MAX As noted by Anssi some 20 years ago, pool report is sometimes messed up. This worked fine on many devices but casued oops on VRS DirectForce PRO. Here, we're making sure pool report is refetched before trying to access any of it's fields. While loop was replaced with a for loop + exit conditions were moved aroud to decrease the possibility of creating an infinite loop scen... • https://git.kernel.org/stable/c/211861869766a7bb7c72158aee0140ec67e182a7 •

CVE-2025-37932 – sch_htb: make htb_qlen_notify() idempotent
https://notcve.org/view.php?id=CVE-2025-37932
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: sch_htb: make htb_qlen_notify() idempotent htb_qlen_notify() always deactivates the HTB class and in fact could trigger a warning if it is already deactivated. Therefore, it is not idempotent and not friendly to its callers, like fq_codel_dequeue(). Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers' life. In the Linux kernel, the following vulnerability has been resolved: sch_htb: make htb_qlen_notify() idempotent htb_qle... • https://git.kernel.org/stable/c/e6b45f4de763b00dc1c55e685e2dd1aaf525d3c1 •

CVE-2023-53146 – media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()
https://notcve.org/view.php?id=CVE-2023-53146
14 May 2025 — In the Linux kernel, the following vulnerability has been resolved: media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer() In dw2102_i2c_transfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach dw2102_i2c_transfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

10 May 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition In btsdio_probe, the data->work is bound with btsdio_work. It will be started in btsdio_send_frame. If the btsdio_remove runs with a unfinished work, there may be a race condition that hdev is freed but used in btsdio_work. Fix it by canceling the work before do cleanup in btsdio_remove.

09 May 2025 — In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix isochronous Ring Underrun/Overrun event handling The TRB pointer of these events points at enqueue at the time of error occurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time we are handling the event, a new TD may be queued at this ring position. I can trigger this race by rising interrupt moderation to increase IRQ handling delay.

09 May 2025 — In the Linux kernel, the following vulnerability has been resolved: um: work around sched_yield not yielding in time-travel mode sched_yield by a userspace may not actually cause scheduling in time-travel mode as no time has passed. In the case seen it appears to be a badly implemented userspace spinlock in ASAN. Unfortunately, with time-travel it causes an extreme slowdown or even deadlock depending on the kernel configuration (CONFIG_UML_MAX_USERSPACE_ITERATIONS).
