CVE-2022-48674

CVE-2022-48674 - erofs use-after-free on UP platforms : Linux kernel patch fixes a race in erofs where erofs_workgroup_unfreeze() doesn’t reset orig_val, allowing a pcluster to be reused after free. This leads to a use-after-free in paths such as z_erofs_do_read_page/z_erofs_readahead under stres...

kernel: erofs: fix order >= MAX_ORDER warning due to crafted negative i_size

In the Linux kernel, the following vulnerability has been resolved: erofs: fix order = MAXORDER warning due to crafted negative isize As syzbot reported 1, the root cause is that isize field is a signed type, and negative isize is also less than EROFSBLKSIZ. As a consequence, it's handled as fast...
