2025-02-26 CVE-2022-49309 Improper Locking vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback() There is a deadlock in rtw_surveydone_event_callback(), which is shown below: (Thread 1) | (Thread 2) | _set_timer() rtw_surveydone_event_callback()| mod_timer() spin_lock_bh() //(1) | (wait a time) ...

2025-02-26 CVE-2022-49312 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8712: fix a potential memory leak in r871xu_drv_init() In r871xu_drv_init(), if r8712_init_drv_sw() fails, then the memory allocated by r8712_alloc_io_queue() in r8712_usb_dvobj_init() is not properly released as there is no action will be performed by r8712_usb_dvobj_deinit(). To properly release it, we should call r8712_free_io_queue() in r8712_usb_dvobj_deinit(). Besides, in r871xu_dev_remove(), r8712_usb_dvobj_deinit() will be called by r871x_dev_unload() under condition `padapter->bup` and r8712_free_io_queue() is called by r8712_free_drv_sw(). However, r8712_usb_dvobj_deinit() does not rely on `padapter->bup` and calling r8712_free_io_queue() in r8712_free_drv_sw() is negative for better understading the code. So I move r8712_usb_dvobj_deinit() into r871xu_dev_remove(), and remove r8712_free_io_queue() from r8712_free_drv_sw().

2025-02-26 CVE-2022-49316 Improper Locking vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open() compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr().

2025-02-26 CVE-2022-49319 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3: check return value after calling platform_get_resource() It will cause null-ptr-deref if platform_get_resource() returns NULL, we need check the return value.

2025-02-26 CVE-2022-49323 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code.

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
