CVE-2025-70100

CVE-2025-70100 affects lwext4 1.0.0. A divide-by-zero in ext4_block_set_lb_size (src/ext4_blockdev.c) can cause denial of service when processing a malformed ext4 image, triggering a Floating-Point Exception or crash due to missing lb_size validation during mount/image handling.

CVE-2024-56548 hfsplus: don't query the device logical block size multiple times

In the Linux kernel, the following vulnerability has been resolved: hfsplus: don't query the device logical block size multiple times Devices block sizes may change. One of these cases is a loop device by using ioctl LOOPSETBLOCKSIZE. While this may cause other issues like IO being rejected, in t...

CVE-2024-56548

CVE-2024-56548 affects the Linux kernel’s hfsplus handling. The root cause is changing device logical block sizes (e.g., via LOOP_SET_BLOCK_SIZE) that can cause a write of out-of-bounds data when hfsplus_read_wrapper calls hfsplus_submit_bio. The fix introduces a new min_io_size, set to the max o...

kernel: block: null pointer dereference in ioctl.c when length and logical block size are misaligned

A flaw was found in the Linux kernel's block subsystem, where a NULL pointer dereference occurs if partitions are created or resized with a size that is not a multiple of the logical block size. This flaw allows a privileged attacker to cause a denial of service...

CVE-2023-52458

CVE-2023-52458 affects the Linux kernel block subsystem where partition length must be aligned to the disk’s logical block size. The issue arises before adding or resizing partitions when length isn’t checked for LBS alignment; if LBS > 512 bytes, the partition size may not be a multiple of LB...
