CVE-2024-56772

The CVE-2024-56772 entry describes a use-after-free in Linux kernel kunit: in kunit_debugfs_create_suite(), if alloc_string_stream() fails during kunit_suite_for_each_test_case(), suite->log has already been assigned and the error path frees the stream but does not NULL the pointer. This leads...

CVE-2023-52921

The CVE-2023-52921 entry affects the Linux kernel’s DRM/amdgpu path, where a use-after-free (UAF) can occur in amdgpu_cs_pass1. The root cause is that the gang_size check is outside the chunk parsing loop, so i must be reset before freeing the chunk data. This vulnerability has been addressed by ...
