CVE-2022-50101

CVE-2022-50101 affects the Linux kernel’s fbdev vt8623fb code. The flaw arises in vt8623fb_set_par(), where a user-supplied value is used to compute screen_size. If screen_size exceeds info->screen_size, a memory write via memset_io() can trigger a supervisor-page fault (kernel crash). The rep...

CVE-2022-50099

CVE-2022-50099 affects the Linux kernel video fbdev Arkfb component. In arkfb_set_par(), user input can set screen_size larger than info->screen_size, risking a kernel page fault (LOCAL, high impact). The mitigation described is to check screen_size before memset_io() and apply the provided pa...

CVE-2022-50094

CVE-2022-50094 relates to Linux kernel spmi trace: trace_spmi_write_begin() and trace_spmi_read_end() use memcpy() with length len + 1, causing a potential stack-out-of-bounds read. A KASAN report demonstrates an out-of-bounds read in trace_event_raw_event_spmi_read_end. The issue affects the SPM...

CVE-2022-50094 spmi: trace: fix stack-out-of-bound access in SPMI tracing functions

In the Linux kernel, the following vulnerability has been resolved: spmi: trace: fix stack-out-of-bound access in SPMI tracing functions tracespmiwritebegin and tracespmireadend both call memcpy with a length of "len + 1". This leads to one extra byte being read beyond the end of the specified...

CVE-2022-50093

CVE-2022-50093 affects the Linux kernel IOMMU VT-d code. The issue arises from using arch_test_bit() with a possibly invalid first argument when NUMA is disabled, causing a potential wild memory access after node_online() returns NUMA_NO_NODE. The fix adds an explicit check for node != NUMA_NO_NO...
