26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc/memhotplug: Add add_pages override for PPC With commit ffa0b64e3be5 ("powerpc: Fix virt_addr_valid() for 64-bit Book3E & 32-bit") the kernel now validate the addr against high_memory value. This results in the below BUG_ON with dax pfns.

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_open/close(): fix memory leak The gs_usb driver appears to suffer from a malady common to many USB CAN adapter drivers in that it performs usb_alloc_coherent() to allocate a number of USB request blocks (URBs) for RX, and then later relies on usb_kill_anchored_urbs() to free them, but this doesn't actually free them. As a result, this may be leaking DMA memory that's been used by the driver. This commit is an adaptation ... • https://git.kernel.org/stable/c/d08e973a77d128b25e01a08c34d89593fdf222da •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: bpf: Fix insufficient bounds propagation from adjust_scalar_min_max_vals Kuee reported a corner case where the tnum becomes constant after the call to __reg_bound_offset(), but the register's bounds are not, that is, its min bounds are still not equal to the register's max bounds. This in turn allows to leak pointers through turning a pointer register as is into an unknown scalar via adjust_ptr_min_max_vals().
