CVE-2022-50746

CVE-2022-50746 affects the Linux kernel’s erofs module where an invalid extent length for uncompressed pclusters could lead to a use-after-free observed by syzkaller. The issue is due to insufficient validation of the extent length; the first inlined-pcluster issue (m_pa == 0) has been addressed ...

CVE-2023-54069

CVE-2023-54069 relates to the Linux kernel ext4 allocator (mballoc). The issue is an overflow in ext4_mb_new_inode_pa() that can occur when computing the end position of ext4_free_extent, potentially overflowing ext4_lblk_t (uint). The fix, as described in the publicly provided documents, refacto...

CVE-2025-68364

The CVE refers to a Linux kernel issue in the OCFS2 filesystem: in __ocfs2_move_extent(), a BUG() was relaxed to ocfs2_error() to avoid crashing the entire kernel due to filesystem corruption. This indicates the root cause was a kernel-crashing error path in ocfs2_move_extent() that could exacerb...
