CVE-2026-64559
In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in PKEYVERIFYPROTK ioctl Explicitly check the buffer length request structure provided by user-space and fail, if it exceeds the buffer size...
CVE-2026-64558
In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in pkeypckmo handler implementation Explicitly check the length of the target buffer in the pkeypckmo implementation of the keytoprotkey handler function. The handler function fails, if the generated outpu...
CVE-2026-64559
The CVE-2026-64559 entry concerns the Linux kernel s390/pkey module, where a missing buffer length check in the PKEY_VERIFYPROTK ioctl allowed a local attacker to provide a request length that exceeded the allocated buffer. The available documents confirm the root cause is a length verification o...
USN-8620-2 linux-azure-fips vulnerabilities
Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...
CVE-2026-64369
A flaw was found in the Linux kernel, specifically within the s390 architecture. When the system attempts to read unaligned data that spans across memory pages, it can trigger exceptions. For memory pages designated for secure execution by the Ultravisor, the exception handling mechanism does not...
