CVE-2021-46982 f2fs: compress: fix race condition of overwrite vs truncate

In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix race condition of overwrite vs truncate posfsstress testcase complains a panic as belew: ------------ cut here ------------ kernel BUG at fs/f2fs/compress.c:1082! invalid opcode: 0000 1 SMP PTI CPU: 4 PID:...

CVE-2021-46982

CVE-2021-46982 relates to the Linux kernel’s f2fs compress path. A race between truncate and overwrite can leave a reference on a page, causing find_lock_page to return NULL after truncation. Root cause involves prepare_compress_overwrite, f2fs_pagecache_get_page, and subsequent truncate_setsize/...

CVE-2020-36775

CVE-2020-36775 affects the Linux kernel’s f2fs subsystem. The vulnerability was tied to a potential deadlock in the f2fs_write_compressed_pages() path, mitigated by using f2fs_trylock_op() (consistent with the approach used in f2fs_write_single_data_page()) to avoid deadlocks. The concrete fix is...
