SUSE CVE-2026-53150

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Reject zero-length property entries in validator tbpropertyentryvalid accepts entries with length == 0 for DIRECTORY, DATA, and TEXT types. A zero-length TEXT entry passes validation but causes an underflow in the...

SUSE CVE-2026-53164

In the Linux kernel, the following vulnerability has been resolved: iommu/dma: Do not try to iommumap a 0 length region in swiotlb iommudmaiovalinkswiotlb processes a mapping that is unaligned in three parts, the head, middle and trailer. If the middle is empty because there are no aligned pages ...

CVE-2026-53150

A flaw was found in the Linux kernel's Thunderbolt subsystem. The tbpropertyentryvalid function, which validates Thunderbolt property entries, accepts zero-length TEXT entries. This can cause an underflow in the null-termination logic, resulting in an out-of-bounds write to memory. This memory...

CVE-2026-53148

A flaw was found in the Linux kernel's Thunderbolt driver. A malicious peer can exploit this vulnerability by sending a specially crafted response that causes the system to write data beyond an allocated memory buffer. This out-of-bounds write can lead to memory corruption, which may allow an...
