CVE-2022-50142

CVE-2022-50142 : In the Linux kernel, the intel_th: msu component was fixed to account for DMA buffers that may be allocated via vmalloc() after the patch set removing CONFIG_DMA_REMAP, which could disrupt the mmapping code during faults (msc_mmap_fault). The described issue arises from a possibl...

CVE-2022-50140

CVE-2022-50140 affects the Linux kernel memstick/ms_block subsystem. The root cause is a memory leak where erased_blocks_bitmap is allocated with used_blocks_bitmap but not freed; the patch adds bitmap_free() in msb_data_clear() to free erased_blocks_bitmap. The CVSS 3.1 base score is 5.5 (MEDIUM...

CVE-2022-50141

In CVE-2022-50141, the Linux kernel component mmc: sdhci-of-esdhc had a refcount leak in esdhc_signal_voltage_switch caused by of_find_matching_node() returning a node pointer with an incremented refcount. The fix adds a missing of_node_put() to release refs when the node is no longer needed, pre...

CVE-2022-50140 memstick/ms_block: Fix a memory leak

In the Linux kernel, the following vulnerability has been resolved: memstick/msblock: Fix a memory leak 'erasedblocksbitmap' is never freed. As it is allocated at the same time as 'usedblocksbitmap', it is likely that it should be freed also at the same time. Add the corresponding bitmapfree in...

CVE-2022-50139

CVE-2022-50139 affects the Linux kernel’s usb: aspeed-vhub component. The root cause is a refcount leak in ast_vhub_init_desc() caused by not releasing a reference from of_get_child_by_name(). The fix is to call of_node_put() on that reference. This remediation prevents the refcount from being in...
