CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-37021 – fpga: manager: add owner module and take its refcount
https://notcve.org/view.php?id=CVE-2024-37021
In the Linux kernel, the following vulnerability has been resolved: fpga: manager: add owner module and take its refcount The current implementation of the fpga manager assumes that the low-level module registers a driver for the parent device and uses its owner pointer to take the module's refcount. This approach is problematic since it can lead to a null pointer dereference while attempting to get the manager if the parent device does not have a driver. To address this problem, add a module owner pointer to the fpga_manager struct and use it to take the module's refcount. Modify the functions for registering the manager to take an additional owner module parameter and rename them to avoid conflicts. Use the old function names for helper macros that automatically set the module that registers the manager as the owner. This ensures compatibility with existing low-level control modules and reduces the chances of registering a manager without setting the owner. Also, update the documentation to keep it consistent with the new interface for registering an fpga manager. Other changes: opportunistically move put_device() from __fpga_mgr_get() to fpga_mgr_get() and of_fpga_mgr_get() to improve code clarity since the manager device is taken in these functions. • https://git.kernel.org/stable/c/654ba4cc0f3ed7c0f08bfb39f66059d8c42943ee https://git.kernel.org/stable/c/2da62a139a6221a345db4eb9f4f1c4b0937c89ad https://git.kernel.org/stable/c/62ac496a01c9337a11362cea427038ba621ca9eb https://git.kernel.org/stable/c/4d4d2d4346857bf778fafaa97d6f76bb1663e3c9 •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39292 – um: Add winch to winch_handlers before registering winch IRQ
https://notcve.org/view.php?id=CVE-2024-39292
In the Linux kernel, the following vulnerability has been resolved: um: Add winch to winch_handlers before registering winch IRQ Registering a winch IRQ is racy, an interrupt may occur before the winch is added to the winch_handlers list. If that happens, register_winch_irq() adds to that list a winch that is scheduled to be (or has already been) freed, causing a panic later in winch_cleanup(). Avoid the race by adding the winch to the winch_handlers list before registering the IRQ, and rolling back if um_request_irq() fails. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: um: Agregar cabrestante a winch_handlers antes de registrar la IRQ del cabrestante Registrar una IRQ del cabrestante es picante, puede ocurrir una interrupción antes de que el cabrestante se agregue a la lista de winch_handlers. Si eso sucede, Register_winch_irq() agrega a esa lista un cabrestante que está programado para ser liberado (o que ya ha sido) liberado, causando pánico más adelante en winch_cleanup(). Evite la ejecución agregando el cabrestante a la lista winch_handlers antes de registrar la IRQ y retrocediendo si um_request_irq() falla. • https://git.kernel.org/stable/c/42a359e31a0e438b5b978a8f0fecdbd3c86bb033 https://git.kernel.org/stable/c/66ea9a7c6824821476914bed21a476cd20094f33 https://git.kernel.org/stable/c/dc1ff95602ee908fcd7d8acee7a0dadb61b1a0c0 https://git.kernel.org/stable/c/351d1a64544944b44732f6a64ed65573b00b9e14 https://git.kernel.org/stable/c/31960d991e43c8d6dc07245f19fc13398e90ead2 https://git.kernel.org/stable/c/0c02d425a2fbe52643a5859a779db0329e7dddd4 https://git.kernel.org/stable/c/434a06c38ee1217a8baa0dd7c37cc85d50138fb0 https://git.kernel.org/stable/c/73b8e21f76c7dda4905655d2e2c17dc5a • CWE-415: Double Free •

In the Linux kernel, the following vulnerability has been resolved: dma-buf/sw-sync: don't enable IRQ from sync_print_obj() Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spin_unlock_irqrestore() with spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite sync_print_obj() is called from sync_debugfs_show(), lockdep complains inconsistent lock state warning.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-38659 – enic: Validate length of nl attributes in enic_set_vf_port
https://notcve.org/view.php?id=CVE-2024-38659
In the Linux kernel, the following vulnerability has been resolved: enic: Validate length of nl attributes in enic_set_vf_port enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE is of length PORT_PROFILE_MAX and that the nl attributes IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX. These attributes are validated (in the function do_setlink in rtnetlink.c) using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enic_set_vf_port expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enic_set_vf_port. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: enic: Validar la longitud de los atributos nl en enic_set_vf_port enic_set_vf_port supone que el atributo nl IFLA_PORT_PROFILE tiene una longitud PORT_PROFILE_MAX y que los atributos nl IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID tienen una longitud PORT_UUID_MAX. • https://git.kernel.org/stable/c/f8bd909183acffad68780b10c1cdf36161cfd5d1 https://git.kernel.org/stable/c/2b649d7e0cb42a660f0260ef25fd55fdc9c6c600 https://git.kernel.org/stable/c/ca63fb7af9d3e531aa25f7ae187bfc6c7166ec2d https://git.kernel.org/stable/c/3c0d36972edbe56fcf98899622d9b90ac9965227 https://git.kernel.org/stable/c/25571a12fbc8a1283bd8380d461267956fd426f7 https://git.kernel.org/stable/c/7077c22f84f41974a711604a42fd0e0684232ee5 https://git.kernel.org/stable/c/f6638e955ca00c489894789492776842e102af9c https://git.kernel.org/stable/c/aee1955a1509a921c05c70dad5d6fc856 •
