CVE-2026-10718

Out of bounds write in openSeaChest’s Trim/Unmap operation in Seagate’s openSeaChest v26.03.0 on all supported platforms allows for writing extra memory describing a range of LBAs to deallocate 16 bytes outside of the allocated space when running this operation...

CVE-2025-40345

CVE-2025-40345 affects Linux kernel USB storage for the sddr55, where new_pba values from the status packet could exceed the computed block count, causing the driver to walk past pba_to_lba[] and corrupt heap memory. The fix rejects PBAs that exceed the block count and fails the transfer to avoid...

CVE-2024-30212

If a SCSI READ10 command is initiated via USB using the largest LBA 0xFFFFFFFF with it's default block size of 512 and a count of 1, the first 512 byte of the 0x80000000 memory area is returned to the user. If the block count is increased, the full RAM can be exposed. The same method works to wri...

QEMU: improper IDE controller reset can lead to MBR overwrite

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L1 vdiskL1...

SUSE CVE-2020-1711

An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block LBA in an iscsicoblockstatus routine. A remote user could use this flaw to...
