CVE-2022-49367

Summary (CVE-2022-49367) In the Linux kernel, the mv88e6xxx DSA MDIO registration path contains a refcount leak. The function of_get_child_by_name() returns a node pointer with an incremented refcount, but of_node_put() is not called when finished, leaking references. mv88e6xxx_mdio_register() fo...

CVE-2022-49350

CVE-2022-49350 affects the Linux kernel in the net/mdio area, where the symbol mdio_bus_init is annotated with init and exported. The combination of EXPORT_SYMBOL with init places code in .init.text, which may be freed after init and lead to a kernel panic if accessed by modules. The public advis...

CVE-2022-49284

The CVE-2022-49284 entry affects the Linux kernel coresight subsystem (syscfg: cscfg_create_device). The issue is a memory leak on registration failure caused by improper error handling in device_register() after device_initialize(); the recommended fix is to use put_device() to relinquish the re...

CVE-2022-49282

CVE-2022-49282 is a Linux kernel issue affecting f2fs quota handling. The vulnerability stems from an incorrect loop condition in f2fs_quota_sync() where cnt should be passed to sb_has_quota_active() to correctly determine active quotas. When type is -1, the compiler may discard the check, potent...

CVE-2022-49281

CVE-2022-49281 affects Linux kernel CIFS multiuser handling: each user has a separate tcon and handle for a cached directory, but on unmount the kernel must release the pinned dentry for every tcon rather than only the master tcon. If not, unmount can emit warnings of in-use dentries. The issue i...

CVE-2022-49271 cifs: prevent bad output lengths in smb2_ioctl_query_info()

In the Linux kernel, the following vulnerability has been resolved: cifs: prevent bad output lengths in smb2ioctlqueryinfo When calling smb2ioctlqueryinfo with smbqueryinfo::flags=PASSTHRUFSCTL and smbqueryinfo::outputbufferlength=0, the following would return 0x10 buffer = memdupuserarg +...

CVE-2022-49227

CVE-2022-49227 : In the Linux kernel igc driver, the ethtool RX-ring reconfiguration path copies an igc_ring structure but fails to reset the xdp_rxq_info member before igc_setup_rx_resources is called. This causes xdp_rxq_info_reg() to be invoked on an already registered xdp_rxq_info, leading to...

CVE-2022-49219

CVE-2022-49219 concerns a memory-leak in the Linux kernel VFIO PCI driver during D3hot↔D0 transitions. If vfio_pci_core_device::needs_pm_restore is set, the current PCI state is saved in pm_save on D0→D3hot and would be restored on D3hot→D0. The code uses pci_store_saved_state() to save state and...
