CVE-2026-89573

A flaw was found in the Linux kernel's device mapper dm array component. A local attacker could exploit this vulnerability by providing specially crafted metadata. This crafted metadata causes the system to misinterpret the size of data blocks, leading to an out-of-bounds read. This memory...

CVE-2026-89574

A flaw was found in the Linux kernel's device mapper dm array component. Insufficient validation of array block headers during read operations allows a local attacker to craft a malicious on-disk nrentries value. This can lead to an out-of-bounds read from the dm-bufio buffer, potentially resulti...
