https://notcve.org/view.php?id=CVE-2025-37820
08 May 2025 — In the Linux kernel, the following vulnerability has been resolved: xen-netfront: handle NULL returned by xdp_convert_buff_to_frame() The function xdp_convert_buff_to_frame() may return NULL if it fails to correctly convert the XDP buffer into an XDP frame due to memory constraints, internal errors, or invalid data. Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect f... • https://git.kernel.org/stable/c/6c5aa6fc4defc2a0977a2c59e4710d50fa1e834c •

CVE-2025-37819 – irqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode()
https://notcve.org/view.php?id=CVE-2025-37819
08 May 2025 — In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode() With ACPI in place, gicv2m_get_fwnode() is registered with the pci subsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime during a PCI host bridge probe. But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger: Unable to handle kernel paging request at virtual address ffff8000816c0400... • https://git.kernel.org/stable/c/0644b3daca28dcb320373ae20069c269c9386304 •

CVE-2025-37817 – mcb: fix a double free bug in chameleon_parse_gdd()

08 May 2025 — In the Linux kernel, the following vulnerability has been resolved: mcb: fix a double free bug in chameleon_parse_gdd() In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.

08 May 2025 — In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: Fix deadlock when using NCM gadget The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit 58f2fcb3a845 ("usb: cdnsp: Fix deadlock issue during using NCM gadget"). Under PREEMPT_RT the deadlock can be readily triggered by heavy network traffic, for example using "iperf --bidir" over NCM ethernet link. The deadlock occurs because the threaded interrupt handler gets preempted by a softirq, but both are protected by ... • https://git.kernel.org/stable/c/7733f6c32e36ff9d7adadf40001039bf219b1cbe •
