UBUNTU-CVE-2023-52737

In the Linux kernel, the following vulnerability has been resolved: btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock VFS lock, it only locks a file range in the inode's io tree. This however can lead to a deadlock if we have a concurrent...

CVE-2023-52786

CVE-2023-52786 affects the Linux kernel ext4 subsystem. The issue is a race in the inline data check during direct IO (dio) writes: ext4_iomap_begin() can observe inline data concurrently with MAY_INLINE_DATA state clearing across a lock cycle, potentially allowing a dio write to proceed in an un...

CVE-2023-52737

CVE-2023-52737: In the Linux kernel, when using Btrfs, fiemap could deadlock with an in-flight fsync due to not taking the inode lock (i_mutex) before fiemap operations. The root cause is that fiemap_fill_next_extent() could fault while accessing user space buffers, which creates a lock-order cyc...
